The 1.2s auto is the damage between White Phosphorus casts. Star it so the rockets keep up with 18,545 attack. It does not buff allies.

Combat ATK on the highest SSR attack column. The printed line stays 18.85% from 0★ to 5★ at skill level 30; the star list is extra ATK on top. Personal. It does not care about monsters or players.

Wasteland Wanderer

Ace SkillLv.31 required

0★: Increases ATK, DEF, and HP by 10%.

5★: Increases ATK, DEF, and HP by 10%.

Personal capstone. Unlocks at level 31 and 4★. The printed line does not change from 0★ to 5★. Unlock it for the 10% ATK, DEF, and HP, not because a new sentence appears at 5★.

Best for / not for

Pick her in Warrior marches that need the attack column and a front-two hit. White Phosphorus is 493.5963% ATK at 5★ on 18,545 attack, with DEF down from 2★. Medium camp. Pair her with a real HP pool in front.

Team

Wasteland Wanderer is personal. It does not buff the row.

White Phosphorus reaches 493.5963% ATK at 5★ and cuts DEF by 15% at 4★.
1.2s auto, so she is not empty between 9.2s casts.

Weaknesses

239,945 HP, last of the 12 SSRs.
No ally buff. Disciple and Wanderer are personal.

Best role

PvPGoodGood. Highest SSR attack plus front DEF shred.
BossGoodGood. Rockets and phosphorus still fire; no monster-only line.
ArenaGoodGood. Same as PvP.
CampaignFairFair. Damage is real; she has no monster passive.
SupportPoorPoor. Nothing for allies.

Verdict

Raise Celeste when the march is Warrior and you need the SSR attack lead. Star White Phosphorus first, take Wasteland Wanderer at 31 and 4★ for the 10% stats, and put a tank in front of 239,945 HP. Do not raise her as a Heavy-style front. Do not expect a team monster line from Disciple.
