[VERIFY which other Thief-tier skills exist — Strong Blade Attack, Ambush, Venom Knife placement uncertain pending in-game tooltip check]
Skill priority for advancing
For the Assassin path, max:
- Hiding (gate for many Assassin/AsnX/GX skills)
- Enchant Poison (gate for Enhanced Enchant Poison + EDP later)
- Double Attack (carries forward as core dagger DPS passive)
Pitfalls
- Investing in hybrid stats too early — AGI focus is the path here
- Skipping Hiding rank-up — locks you out of stealth-gated skills downstream
