PascalLimited

Pascal is an Iron Supporter Rocket Launcher who heals the 3 allies with the lowest remaining HP at Burst stage 1 and when she uses her Burst.
She fires in cycles of 10 shots, and Skill 1 gives extra healing to the 1 ally with the highest DEF.
Her Burst cooldown can be a drawback in PvE, but in PvP she is a decent healer.

Completing a cycle of 10 shots triggers Skill 1, healing the 1 ally with the highest DEF based on her own final Max HP.
On entering Burst stage 1, Skill 2 triggers, boosting HP recovery received by the 3 allies with the lowest remaining HP for 10 seconds.
Using her Burst, on a 40-second cooldown, instantly heals 3 targets chosen the same way, buying time for the squad to hold out.

Keep her on auto by default during battle, but press her Burst so healing for the 3 lowest-HP allies lands first.
If late Burst healing keeps causing crises in PvE, manually bring her Burst forward once more to create a healing window together with Skill 2.

Healing Cube boosts the healing received itself, and Vigor Cube raises the final Max HP used for healing. Tempering Cube reduces damage taken, extending how long the squad holds out until healing is needed. If Harmony Cube levels differ greatly, use the higher-level cube over the ranking.

There are few stats that directly boost healing, but support survival with Increased DEF and put remaining lines into Max Ammo to reduce gaps between reloads and Skill 1 triggers.

Prioritize Skill 2 and Burst, which have large healing amounts. Skill 1 is a support role giving extra healing every 10 shots, so keep it at a mid level.

In PvE, the 40-second cooldown can break healing timing and become a drawback. In PvP, she serves as a healer who keeps allies stable when Burst healing lands on time. In long engagements like boss fights, Skill 2's 10-second healing boost and Burst healing build cumulative value.

Through Burst stage 1 and her Burst, she steadily heals the 3 allies with the lowest remaining HP.
She fires in cycles of 10 shots, so Skill 1 also gives extra healing to high-DEF allies.
As an auto Rocket Launcher, she has little charging burden, helping sustain her healing cycle.

Her Burst healing is tied to a 40-second cooldown, so timing may not line up in short PvE fights.
Skill 1 only heals the 1 ally with the highest DEF, so it does not always reach the ally who urgently needs healing.
She is a healing-focused unit, so do not expect fast clears from her attack alone.
