Kraken hits without animation?

[DGDobrev]

Well, I'm just doing the kraken fight in champion of the arena with a single stack of royal thorns. I did the usual troll strategy - put the thorns between two tentacles, but this time, I decided to kill the left one so that I can hide in the corner and have only 2 stacks of devilfish attacking me.

That turns out to be wrong. I suffer hits by the kraken as well, but there is absolutely no animation, no tentacle swing or slap, no water splash, nothing to indicate an attack - only the damage numbers show up.

EDIT: HMMMM. BUMMER. I have noticed something else that kinda makes me consider this a bug. When the no-animation kraken attack happens, the royal thorns do a retaliation animation (they also hit, but hit the thin air, no damage numbers appear). That's not good... At first I thought some of the devilfish do that, but that's not the case because no damage numbers show up - EDIT: as you can see from the third screen, the thorns do look a little odd, as if they just attacked.

EDIT: Oh-kay... I made another screenshot, which clearly shows that I am being hit by an invisible tentacle. Although this is not recommended for the thorns strat, I used the royal thorns to summon some reinforcements - and guess what - the invisible tentacle promptly hit both stacks, as you can see from the 4th screenshot.

The first screen indicates my position, the second one I made for the battle log, where you can see I have suffered a hit in this position. The third screenshot shows the hit of 299 damage and the fading out devilfish hit for 50 something damage, which is not a concern at all. As you can see, I suffer this hit as soon as the adrenaline animation appears.

Is that supposed to happen? It's as if the destroyed tentacle is still slapping my poor thorns If this is not supposed to happen, I guess the only way around it is to do the tactic of 1-hit tentacles (use spells to drop all tentacles to 1-hit kill while hiding between any 2 of them so that only a single stack of devilfish can attack you).

Rather weird.
