The ability sharp is working?

[Daniel7Sly123]

I'm trying to complete formicarium challenge 3 and i spent my royal jelly on a skill for taunt major "SHARP" the description says aura but I never see the aura show up, I suppose it's similar with that aura of army ants soldiers. But I've never seen this happen or my ants using this ability even though the aura does not exist.
I´ve never see that aura, is the entire skill not working or is working but the aura do not appear?

I think "aura" just means that it applies over an area. It's not supposed to have a visual effect.

It'd be kinda cool if it did, though.

I agree it should have a visual effect, just was not time to get them in within time. I also think thorns should cause some visual effect to the attacker so you know. Will jot it down
