For more Desert Titan taming details, get the taming calculator app.
To tame a Desert 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.
You know what I find odd? The three titans (not including the king) are supposed to be super hard bosses, and they are, but if you look at their health stats in comparison to other bosses.... ice titan 350k, desert is 250k and forest is 400k. 350k+250k+400k=1million. Roughly the same amount of hp as the alpha broodmother, less than alpha rockwell, similar to alpha moeder and the alpha crystal wyvern queen. And you can’t bring more than 20 tames into those fights, and you can’t bring gigas or meks either.
