The Arena power feats make the half-elf's dilettante power even more appealing. Also, the savage armor would be really appealing if it was a cloth or leather armor; a squishy type wearing that and suddenly shoving everyone away to escape? Priceless.
Here's my rules question: the daily powers for the Net and Whip say target is grabbed/knocked prone/etc (save ends). Then it says "You can sustain this power as long as you are within 5 squares from the target."
What does sustaining a power do when it has a save ends effect? Does that mean that, as long as you sustain, the save doesn't matter?
