I’m not sure if you are planning to add a skilltree to Teleport, but if you are, please consider adding the following utility;
“Teleport can now be cast while casting another spell.”
Right now, it feels awkwardly clunky to cast teleport when in combat. Basically it is nonresponsive if you cast anything else, which can be quite dangerous. I can understand the idea behind it, but adding this utility node would be worth while. If you don’t plan to add skillnodes at all, then consider changing this.
