Strategy Guide

Ksai is a Fire Ranger boss that heavily favors Water units. Non-Water units suffer Attack and Defense penalties, while the entire team receives Debuff Enhancement. The DoT cap makes Curse and fixed damage strategies less effective, limiting damage to 5k per tick. This boss can be cleared in a single run with proper Water-focused team composition.
