If you only care about PvE, reset the units that are no longer part of your tower, raid, or bossing teams and keep the ones you still need for those roles. Skill uninstallers stack, so if you are unsure about a unit, you can hold them until the next reset cycle instead of spending them now.
What Skill Uninstallers Let You Do
Skill uninstallers arrive through in-game mail and can stack, letting you hold multiple and use them as needed. If you are not confident about resetting a unit yet, it is valid to save uninstallers for future reset cycles rather than spend them immediately. The current reset window has been roughly every half anniversary or anniversary.

A Skill Reset window is open over the character menu, with skill icons, reset cost, remaining time, and a reset button visible. — skyjlv
prerequisites
- Skill Uninstallers from mail (they stack in inventory)
- Any unit you plan to reset
- Check reset window (cycle has recently been every 6 months)
- Decide which units are safe based on PvE usage before spending
Which Units Still Matter in Tower Teams
Tower unit priorities depend on which teams you still run for specific towers. Reset units that are only temporary picks or are used in fallback setups. The following table gives an overview of which units still matter for each tower.

The Missilis unit list is shown in a Google Sheets guide, with Tia and Naga visible among the icons. — skyjlv
| Tower | Core units | Alternate/Fallback | Reset if only temporary |
|---|---|---|---|
| Elysion | DKW, Maids, Red Hood, Helm | Vesti (if using Rapi), Rapi | Units not used in current team |
| Missilis | Tia, Naga, Liter | Mihara (off burst) | Remove Tia only if not needed |
| Tetra | Anis (optimal B1) | Moran, Rouge, Bunny Aid, Bunny Milk, Blanc, Summer Rosanna, Alice, Volume | Volume (if just a fallback) |
| Pilgrim | - (flexible, overlap with campaign) | Maid Mast, Privaty, Anchor, Helm, Moran, Rouge | Temporary picks not used elsewhere |
If you have invested in fallback or temporary units (like Volume for Tetra), they are reasonable reset candidates if you now have the core units covered elsewhere.
Keep These Raid Burst 1 Units
Certain burst 1 units remain essential for Solo Raid and Union Raid, while others are flex picks or now best reset unless you still need them for another PvE role.
A Google Sheets guide displays the Solo Raid / Union Raid burst 1 list with core unit icons and category labels. — skyjlv
Raid Burst 1 Unit Reset
- Keep Anis, Siren, Moran, Miranda, Stove for shotgun teams; these are core burst 1 units.
- Keep Liter, Red Hood, Rouge as flex burst 1 picks for HP race or pierce compositions; keep Summer Helm (iron advantage) and Winter Celine (shotgun) for element matchups.
- Lower priority burst 1 units are strong reset candidates unless you need them elsewhere in PvE. Reset older or unused burst 1 units unless they are still vital in your tower, campaign, or bossing setups.
- For DKW, keep only if used in Elysion Tower; otherwise reset if not needed for raid content.
Burst 2 Units: Core, Elemental, or Safe to Reset
Raid burst 2 unit priorities are framed below. Crown, Nita, Bunny Aid, Grave, and Blanc are still strong for bossing, while others are increasingly dated or only situationally needed.
A spreadsheet guide shows Burst 2 unit categories with character portraits arranged into groups, including a blue-highlighted portrait near the top. — skyjlv
| Burst 2 unit | Role | Elemental/team-specific | Reset candidate |
|---|---|---|---|
| Crown, Nita | Core bossing | - | Keep |
| Bunny Aid, Grave, Blanc | Strong bossing | - | Keep if used |
| Winter Bride, Arcana FM, Velvet, Tohru, Maids | Elemental advantage | Team-specific | Reset if not used |
| Mary, Summer Rosanna, Leona, Trina, Guilty, Yulha | Niche/high investment | - | Reset for raid-only |
| Tia | Missilis Tower | - | Keep if tower matters |
Invested burst 2 units from last cycles (Mary, Summer Rosanna, Leona, etc.) are safe to reset unless you still heavily invest for niche raids. Tia remains valuable in Missilis Tower.
Burst 3 Units Worth Keeping for PvE
Certain burst 3 damage dealers retain PvE value, but several legacy or element-specific units are now mostly reset candidates unless you need them for another role.
| Burst 3 unit | Element or role | Status | Reset candidate |
|---|---|---|---|
| Rupee (fire), Rupee, Diesel, Mihara | Fire, general | Core | Keep |
| Drake, Alice, Fire Rapi, Modernia | Flex DPS | Flex | Keep if used |
| Vesti, A2, 2B | Fire raid | Fire-specific | Reset unless needed elsewhere |
| Yulha, Snow White, Dorothy Treasure, Helm Treasure, Summer Anis | Water | Core | Keep for water advantage |
| Ludmilla, Bunny Soda, Quincy | Water | Flex | Keep for bossing situations |
| SBS, Liberalio, Wind Asuka | Wind | Core | Keep |
| Wind Rapi | Wind support | Support | Keep if used |
| Neon, Cindy | Electric | Core/support | Keep |
| Isabel, Aida, Jill, Scarlet, Maid Privaty, Guillotine, K | Electric | Niche/dated | Reset unless filling a key DPS or synergy |
| Laplace, Maxwell, Julia, Sugar | Iron situational | - | Reset unless massively invested |
Legacy burst 3 units are generally safe to reset if no longer used outside raid teams or if their element is no longer needed.
Units to Reset Only With Caution
Also worth knowing
- Skill uninstallers stack: You can hold all unused uninstallers and save them for future reset cycles if you are unsure about a unit.
- Reset cycle timing: Skill uninstallers are now distributed around every half anniversary or anniversary, not every few months.
- PvE-only scope: The recommendations above are specific to PvE content; PvP team priorities require a separate list.
FAQ
Which units are safe to skill reset if I only care about PvE?
Units that are no longer part of your tower, raid, or bossing teams, or are only temporary picks, are safe to reset. Keep core units and those still needed for any PvE role.
What are the core Burst 1 units for Solo Raid and Union Raid right now?
Core burst 1 units are Anis, Siren, Moran, Miranda, and Stove. Flex picks include Liter, Red Hood, Rouge, Summer Helm, and Winter Celine for specific teams and elements.
Which Burst 2 units are still worth keeping for bossing teams?
Burst 2 units to keep are Crown, Nita, Bunny Aid, Grave, and Blanc. Elemental bossing units (like Winter Bride, Arcana FM, Velvet, Tohru, maids) are situational and may be reset unless needed.
Which Burst 3 units are considered core, flex, or outdated for PvE?
Core burst 3 units for PvE are Rupee, Diesel, Mihara, and water units like Yulha, Snow White, Dorothy Treasure, Helm Treasure, Summer Anis. Flex picks include Drake, Alice, Fire Rapi, Modernia, Ludmilla, Bunny Soda, and Quincy. Outdated or niche units (Vesti, A2, 2B, Isabel, Jill, Scarlet, K, Maid Privaty, Guillotine) are safe to reset if no longer used.
Should I reset DKW, Tia, Vesti, or Volume for raid content?
DKW and Tia should be kept if you still need them for Elysion or Missilis Tower. Vesti should only be reset if she is not used for Elysion Tower, campaign, or PvP. Volume is safe to reset if just a fallback for Tetra and not needed elsewhere.
Are the creator’s recommendations meant for PvE only or also PvP?
