Unless is has changed, which I suppose is possible, there’s a 1% attack boost and a 10k attack multiplier for Death Gaze. Perhaps the damage type is not “pure” (i.e., maybe it is based on the element of the attacking dragon). So, there could be other factors that are reducing the damage of the spell in a given test.
However, this is a great illustration of the problem of scaling. I’m sure that even a year ago, no one thought a 10k multiplier would not be sufficient to cause immediate death of a structure.
If we look at the wording of the spell descriptions, there are only a few spells that, based on the description, guarantee death. DG, in a bit of an oxymoron, is not one of them:
DG --Dragon’s next attack deals enough damage to destroy most buildings instantly
Umbral Spike – A shadowy spike emerges from the ground and pierces the targeted tower destroying it. Clearly states destruction.
Uproot – Wooden spike destroys the targeted tower and restores health. – Clearly states destruction.
Elemental Flux – Next attack kills one building instantly with an elemental blast. – Clearly states destruction.
Death Stare – Dragon’s next attack deals enough damage to destroy most buildings instantly
Spell Flux – Explodes one tower and damages nearby towers – Clearly states destruction
I think that’s all the one-shot abilities. If I missed one let me know.
I left out C2D intentionally, since it’s not technically a one-shot.
I think it’s just going to require a different tactic. Is it really reasonable to think a level 6 (or a level 1) dragon with DG could kill and end-game tower with boosted HP? That seems just a bit of s stretch to me. I do understand the frustration, but I don’t see it as a deal-breaker. Maybe another straw on an every-growing stack, but it’s not the one that will break my camel’s back.
