Allos have the speed of a carno and the strength of a rex; a well-rounded creature to go for. In packs of three or more, the highest lvl allo will become the alpha (the one with the cheeto dust cloud), which can do bleed damage that deals DOT and slows down a target. Definitely recommend mass-taming for PvP.
This dino is by far my favorite. If you can manage to find 3 120 allos you will be close to unstoppable. When you have 3 allos( doesn't matter what genders) the highest level will be considered the "alpha", this means the alpha can do bleed affects which causes damage over time as well as slows you down temporarily. When getting a pack of allos or a allo the only stats that ever need to be pumped is stamina, melee damage, and movement speed. Hope this helps! 😄
