quite alot i think...

Deviljoe dont need to be scared by its speed. just stay under his belly ALL time. almost all his attacks won't hit u under the belly (although some seemed like it will, but nope). just be careful of the occasional single foot stomp, that WILL hit u if u under his belly, but he gives quite obvious signals before stomping, so shud be ok. after finishing off deviljo, there comes the hard part.

bring ur bag full of smoke grenades and flashbangs and materials to make them. engage naruga, throw smoke grenade and pray that tigerex dont see you. if it does, flash bang him and continue spanking naruga while maintaining smoke and flashbang whenever needed on tigerex, till naruga dies (HP freaking short, low level's HP, just the attacks are hi-level).

things to take caution: when tigrex is blinded he occasional push rocks that will accidentally hit u, keep your eye on him and move behind naruga to use him as shield while continue spanking.

then tigerex is all yours. good luck!
