My current main build for [Yareli] that I've played way too much since her release. Made without dump stats so that all abilities are still usable when the situations they work in pop up.

This build works passably up to around lv100 (non steel path) for most enemies. Infested will be easily vaporized by riptide even on steel path and that ability can be used to group enemies up, though that works better with low ceilings. I would replace aquablades with gloom, but that does not work with merulina at all so currenty i simply do not use that ability, its a complete waste of energy. Even activating gloom before merulina will not work. The ability remains active but does nothing.
Pair it up with a crit heavy sporcelacer to take it further by making use of Yarelis passive. With that setup it can go into steel path and be fairly good once you get enough practice with merulina. Older tilesets do unfortunately have bugged doors that kill all momentum when going through them, which should be considered. To survive you must never stop moving and abuse the movement evasion chance.

Ill see about updating this whenever the inevitable buffs are released.
