How to Get Unbound Kokushibo in All Star Tower Defense X?
Unlike Unbound Esdeath (Etri) that you can grind through Trials, getting Kokushibo is pure RNG. Here’s the brutal truth – there’s only ONE way to obtain this Upper Moon demon:
The Summon Method (Your Only Option)
Step 1: Navigate to Summon Area
- Click the Warp button on the left side of your screen
- Select “Summon” to teleport to the banner area
Step 2: Choose the Right Banner
- CRITICAL: You MUST roll on the Y banner
- Kokushibo is NOT available on the X banner
- Many players waste thousands of gems on the wrong banner!
Step 3: Prepare for the 0.01% Odds
- Each single summon costs 50 gems
- 10x summons cost 450 gems (10% discount)
- Statistically, you’ll need 10,000 summons for guaranteed drop
- Use ASTD X codes to maximize your free gems
Step 4: Watch for the Cutscene When you finally pull Kokushibo, an exclusive cutscene plays showing him in his iconic pose. This cutscene ONLY appears for Kokushibo – if you see it, congratulations!
Maximizing Your Summon Chances
Based on my experience and community data, here are proven strategies:
- Save for 10x Summons: Better overall value and pity system progress
- Track Pity Counter: 100 pulls guarantee a 5-star (per banner)
- Join Events: Special banners sometimes increase Unbound rates
- Use All Free Gems: Complete daily tasks, story mode, and challenges
