hello we are currently playing an RTL session and a question arose

a leaping blood ape how many damage take entering shiver's aura?

4 every space including his front and rear or just his front ?

(i.e. the blood ape is leaping and technically he take 4 damage for his front or just 8 front and rear for each space?)

Lord Loren Soth said:

If the Blood Ape is doing a leap attack and 'jumping over' Shiver, it takes no damage from the aura.

GLoAQ says:
Leap and Berserk
When using the Leap attack, are Blood Apes affected by Aura? Also, are they affected by abilities such as Alertness and Guard orders, which can be triggered by a figure moving next to the Hero with the ability?If the Ape is affected by Aura when it has Leaped, does it gain the benefit of it's Enrage ability from the Damage taken?
No, No and No

and what about a big monster entering shiver's aura?

does he take damage with only front space or even it's rear space?

A figure can only be damaged by Aura once for each movement , but it can be damaged if any part of its base touches an affected square.

So if a large figure takes a single step that causes two of its squares to be adjacent to Shiver at once, it's only affected by the Aura once. But it's still affected if it makes a movement that puts its "back" part adjacent to Shiver even if it's "front" half is not adjacent.
