Feat: Mobile Thralls

Your thralls can now follow you wherever you go. Any thrall you create has your choice of a climb Speed or swim Speed. The additional Speed is equal to its land Speed, and any time you let the thrall Stride, you can have it use the relevant movement action instead.

At 8th level, add a fly Speed to your choices. A flying thrall remains airborne at the end of your turn even if it didn't Fly that turn.
