How do I use the warp stones

[elric999]

Cool game but I am half way done and I cannot figure out how to use the warp stones. Where are the "way points" or warp points in the game?

Use the warp stone near any of the places u save the game to open up a portal to town.

Okay look go enar one of those save point things on the ground, and toggle up a warpstone in your magic thing, then use it and it makes the thing go all funky and rainbowish, then step on it and it asks u if you want to go back to town, then you appear in the guys shop and go back at your leisure
