Got it from a lizard event a little while back, and I only just got round to trying it out.
I tried it on Johnny Rook first, and it did fifteenish physical icons and healed 5% - I wasn't massively impressed.
then I tried it with Worsening, and the number of icons seems to go up with... level? Intelligence? Anyway, Worsening is doing 30 icons with it, and it's healing between 5% and 20%. I'm really rather pleased with this.
i've been playing with it more and it seems to heal between 1 and 20% - I thought the healing might be dependent on the pet's strength, but I think it's actually random.
The damage done does seem dependent on the pet though, it's the same every round and Worsening is doing a LOT more icons with it than my weaker pet did.
...I love this thing.
first turn vs lindorm
You froze your opponent! You strike with the gunblade at perfect accuracy!
You strike your opponent with this beautiful gunblade to cause damage off the scale!
45
and 1% heal
second turn
no freeze
45
and 5% heal
third turn
freeze again
45
and 20% heal
really nice
What the crap, it freezes too? And it didn't stop me equipping it with the Deluxe Death Shard.
Though I think Worsening isn't big enough to freeze with it yet, maybe. It clearly gets better as you go.
There was already a board about this a while back,
Its Int Based
Had to try it with my pet Legend. ^^ (BTW, it's NOT good to test against M4-L155. ^^; Forgot about his physical reflector. Switched to Oslyae.) Level: 205 Health: 503 Strength: 503 Defense: 503 Intelligence: 503
blinks Didn't realize my stats were so even.
35 Physical 19%,3%, 3%, 15%, 12%, 7%, 13%, 13%, 1%, 15%, 2%, 19%, 8%, 9%, 10%, 8%, 2%, 3%, 15%, 18%, 10%, 16% heal
Seems to be in the 1-19% healing range. No freezes for me, unfortunately, Must be unlucky?

Freezes probably only once you get to 45 icons.
Oh, wowww. I would lovelovelove to have this, but my strongest pet isn't that strong, yet. I think it would only do 15 icons. :/
