Form my test Adamantoise is seem like to Slugs pet it's very high resistant to water base magic, I bring it try with VNM T2 Yacumama, It's get hit form nm en-water like 0-2 dmg (i use 1 food to kill this) , also it's very ideal pet to tank Krabkatoa, when i try it's very resist to bubble shower and also i really feel that it's resist to poison form venom shower, i think with Harden Shell it's may bet for nice tank pet in some case. too bad i run out of pet food (left only 3 when start fight it) else i think it's very possible to solo Krabkatoa with some of jug. The worst point of this turtle is it's movement speed is very slow, even no any movement speed i need to keep wait it.
