Tethra

The Tethra sword aplies its def ignore when using this skill??

If you are attacking, yes. Otherwise I would think the clones themselves attack with the skill's properties. I do not actually own one to thoroughly test.

I attacked the boss of Fomor Attack with the Rusted Long sword equipped and his protection went down noticeably, so it's safe to say that any properties carried by the weapon (Poison, Elemental, ect..) is also carried by the clones' weapons.

It would need more testing but seems like good info thanks guys :3

Easiest way to confirm would probably be to use the skill with a Caladbolg.

Because the easiest way would be to obtain a weapon that costs 6x+ more and does not have the same effect.

Hm, i can test using a caladbolg if you wish.

Why not test with a poison weapon instead? It's a lot easier to get.

Can't really tell if poison is applied twice.
