For full Forest Titan taming details, get the taming calculator app.
To tame a Forest Titan, you must destroy the corruption on its body. Taming effectiveness will drop if you hurt the Titan, so try to focus on the corruption. Titans come pre-equipped with a Platform Saddle, however, they are piloted from a seperate cockpit. Titans are a 24 hour temporary tame.
Pro tip: Don't use explosive weaponry and really bad rexes with no saddles like the devs did. Fab Snipers for taming it with little/no collateral damage, actually decent rexes + imprint + saddles to kill it
Try to hit the coropted glowing things around his body. Ice you have destroyed all, it should fall down on the ground knocked out. You do not need any taming food for it, Just go up to it and click tame to tame it. No need to build a saddle because it already comes with one.
Easiest kill of all titans 400 metal arrows from a 200% comp bow and 45 min use the forest wyverns to finish it if you fall a bit short have 4 beds near it “I didn’t die once” can drop quality tek and Mek part bps
Probably the best of all the titans for farming OSDs - the vine grab can be used at range to both draw away almost any corrupted creature (except wyverns for some reason) and deal massive damage to them without damaging the drop itself. Have a few turrets for point-defense against close-range flyers (have had trouble with these in the past) and you should be able to get through most drops without damaging them too much.
