Floater skills are bugged in v0.32.
1. Float is supposed to "target self" but it instead "targets 1 foe". This is caused by a typo in Skills.json on Line 177 where the "scope" field has a value of 1 instead of 11.
Float also applies a -10% AGI debuff but its status effect icon displays it as a buff to AGI instead. Not sure if it's intended, but it's confusing.
2. Gas Leak works as intended when used by enemy Floaters. The child Floater can never learn it though, because of a typo in Classes.json on Line 14 where the array containing "level":6 has a "skillId" value of 174 instead of 176. Skill 174 is High Pressure Air Shot, which is already learned at Level 2.
Fixing the typo in Classes.json will allow the child Floater to learn Gas Leak once it reaches Level 6. But this doesn't work on saves where the Floater is already Level 6 or higher before the fix, so future patches should incorporate some way of fixing this retroactively (via dialogue option, item or making Gas Leak teachable to Floaters).
Kinda of a shame because it's a pretty nice AoE skill with a low TP cost.
