Left click
Bite
Left click performs the simple bite. It is cheap, can be used while chasing, and helps tag a small target in front of you, but it is modest compared with the rest of the kit. Bite is the clean option when you do not want to spend stamina or slow down.
Alt + left click
Claw attack
Claw attack is triggered with Alt + left click. Official notes add bleed to Tenontosaurus claw/kick attacks, so this is often better than bite when a small or medium predator stays in the front angle. It chains more easily than heavy hits, but Tenonto's real defense is still keeping enemies where kick and tail slam become possible.
Right click
Rear kick
Right click triggers a powerful rear kick. It directly punishes predators sticking to the rear or trying to exploit the pivot. Official notes confirm control on this move, so save it for the moment the enemy has truly committed instead of throwing it into empty space.
Alt + right click
Tail slam
Alt + right click triggers tail slam, the heavy control tool. It is slower and more expensive than bite or claw, but it can break enemy tempo, push or stun depending on the target, and open a window to recover position. This is a punish button, not a panic button.
Camera + movement
Angle correction
Tenonto lives on angle correction. It should walk, turn, watch the threat, and swap attacks based on enemy position. A good player does not spam: bait an entry, correct the camera, strike with the right side, then recover enough space to repeat.
