Universal Tower Defense Update 0.5 How to Unlock Ichigo Guide
Grinding spirits and unlocking Ichigo in Universal Tower Defense can feel slow if you pick the wrong mode. Since Update 0.5 dropped, there is one method that clearly beats the rest in terms of time, consistency, and overall progress. This guide breaks down the fastest way to farm spear souls while pushing pity for Ichigo without wasting long runs. Also check out our Universal Tower Defense Codes & Tier List for more rewards!
Why Act 5 Raid Is the Best Choice
After Update 0.5, players have two main options: Boss Rush or normal Raid Acts. While Boss Rush looks tempting because of higher rewards, it takes much longer to clear. Act 5 is the real winner here.
Act 5 can be cleared in around 3 to 4 minutes per run. Boss Rush usually takes close to 10 minutes. Even though Boss Rush has slightly better gem rewards, Act 5 lets you run three times in the same time window. That means faster pity progress and more total spear souls per hour. On average:
- Act 5 gives around 22–30 spear souls
- Boss Rush gives around 19–25 spear souls
When you factor in speed, Act 5 gives more souls overall.
Where to Start the Grind
Head to the Raids section, located near the summon area or inside the Areas menu. Talk to Nell to access the raid list. Choose Act 5 and repeat it as fast as possible. The goal is not perfect rewards, but fast clears. The boss spawns around wave 15, and once the boss is defeated, the run ends early. You do not need to reach wave 20, which makes this raid even faster.
Best Unit Setup for Fast Clears

You do not need multiple rulers to make this work. One strong setup is enough. Recommended roles:
- Farm/Speed Cart: Upgrade early to speed things up
- Air or Hill Unit: Very important for early waves
- Main DPS: Any strong boss killer works
- Buffer: Units like Meiku help boost damage
- Slow Unit: Ragna is great for slowing the boss
Bleach units like Herabel and Kachi are highly recommended because they get a 30% buff from the Peroxide tag in this raid. This buff makes a big difference in clear speed.
Placement Tips That Save Time
Place your main AoE DPS in spots that hit multiple parts of the track. Avoid placing everything too far at the front, since the Ichigo boss has high HP and usually survives long enough to walk deeper into the map. Slow units should be placed near the middle so they affect the boss for as long as possible. This helps your DPS melt the boss before it reaches the end.
Why This Method Reaches Ichigo Faster
Even though Act 5 has a slightly higher pity count, the short run time makes it much faster overall. You will reach pity quicker simply because you are clearing more runs in less time. If you play with friends, you also get a bonus drop chance, making this method even better.
If your goal is to farm spear souls and unlock Ichigo as fast as possible in Universal Tower Defense Update 0.5, Act 5 raids are the way to go. Short runs, solid rewards, and fast pity progress make this method far more efficient than Boss Rush. Stick to this setup, repeat runs consistently, and Ichigo will be yours sooner than expected.
