NGU Idle Wiki

It's big, it's heavy, it's wood!

Grand Corrupted Tree is the second titan, and is likely a reference to Yggdrasil, which can be unlocked after beating this titan. It is the second titan, unlocked after beating boss 66 (Sundae).


GCT will also get slightly stronger over time, but this may not be as noticeable as in GRB's (Gordon) case. The tree will do a lot of damage even on the beginning of the fight, but your health can be sustained up until the end by using "Block", "Parry" and Buffs as much as possible.

GCT can release 2 types of spores, one that reduces your attack ("Your arms feel heavy") and the much more dangerous one that reduces your toughness by a considerable amount ("You feel the energy draining from you"). Try to use block and/or defensive buffs when you see GCT use toughness reducing spores.

Because of GCT's spores, you may fail a few times due to it casting a lot of energy draining spores.
