Araneo needs some TLC
I like the Araneo its lots of fun, easy to tame and is kind of useful but not really. However I think it needs some TLC.
Its web ability is great and really its only redeeming feature. It would make more sense if it could climb on walls as it is a spider. Perhaps losing stamina if a player is on its back.
Another suggestion is a "grappling hook style" web attack. It fires a line of web that if it attaches to a wall the Araneo can use that to rappel up and down. But if it hits a small tame or a player then they could be dragged back to the Areneo. It would be so much fun waiting in ambush up on a ceiling ready to web an enemy player or tame you wish to passive tame. Probably a bit over kill but once you have fired a web line you could attach it to the surface the Araneo is on and have a temporary zip line. Or if you have captured a player or dino you could attach them to a surface and leave them as bait or so you can passive tame the creature.
