Err, and what's the point of this skill? A little bit of extra damage only to hit less often. How about... Attacks only deal half damage, but cannot be miss or be blocked or be evaded? That might be worthy of an elite.
25 damage on every attack is very high. But hiting less balances this. Imagine this elite combined with Sand Shards. Damage every hit! I would make it more than 10 attacks only though.
Sorry but that's a horrible idea for an elite skill...The damage balances out to normal damage if not even less. I wouldn't even take it if it was a regular skill...
