Yuuna overview
With some items she removes enemy backliners efficiently through early encounters. Her preferred route turns those kills into economy, after which she can be sold when her damage falls behind. Against the dragon, her cast moves her next to the boss and often gets her killed.
How to use Yuuna
Game plan
- Use her to remove vulnerable backliners and earn shards in Act 1.
- Sell her when she stops securing kills in Act 2.
- Avoid relying on her as the dragon carry unless a much higher-rank copy appears.
Items
- Give her enough early damage to finish backline targets, but avoid permanent over-investment in a planned sale.
Positioning Aim her toward enemy backliners in normal encounters, but do not let her ability placement become the team's dragon plan.
Source limits The chapter supplies no detailed stat-by-stat item priority. Her ability movement is a major liability against the dragon.
