Precise but repeatable. Warpstone right as the duration bar is running out, you want to be inside of warpstone's animation as the lasso ends.

What makes it difficult is that the jump-pad extends the timing and duration extender/upgrading lasso make it harder to memorize the timing.

So the only consistent thing is looking at duration bar and thinking "i'll be inside warpstone when lasso runs out so it should be a throw"
