No cheats/Legit Solo Killed the Forest Titan easily with a Max Lvl Managarmr.
Mana stats: Mom & Dad Mana were both max lvl with high points in damage. I trained my "Boss Managarmr" Mana-4 by killing corrupted on OSD/Vein defenses. It currently has 72 level ups all put in damage.
Server Stats: Max Lv-240, increased rates for harvesting & breeding.
PS: I had thought of using my upcoming imprinted Giga army but that would be too easy & time consuming. I am saving them for the Ice or finally the King titan.
