If to much damage is taken it will throw you away so have a parachute ready

Knock out beavers so you don't have to get killed when gathering

relatively easy trap: 4 stone floors going in a box or square shape, then 2 stone doorframes high placed on top of the floors, leaving no spaces behind (16 doorframes), then two wooden ramps placed on any side of the doorframes. next, lead the Rex inside the trap and escape using the open doorframes. I recommend prime meat (will usually take narcotics, but I prefer biotoxin to keep them sleeping) or the kibble needed for the Rex.

please don’t challenge a giga with a Rex.
