get rid of teleport items or at least make them more expensible slow the movement (even more) and he is balanced:
-he might be stronger then the other demigods in 1v1 but
-he is slow so when his health gets critical he needs a lot of time getting back and heal
-no teleambush so you can evade him or choose not to fight, since all other demigods are faster
-since he is so slow he would not be so flexible
-he would be what he was meant to be (at least in my understanding) a lane pusher, a giant walking castle
