How to read the AS?

Gozu's picture

Is it just weird wording or should it be understood as: 4x120% earth dmg to nearest, 3x120% earth damage to 2nd nearest and so on?

Not in that order, but total.

Not in that order, but total. That's how I read it.

This can probably affect who the targets will be in the successive batches. Let's label enemy party A B C D E, and let's say three strikes would be enough to kill any of them (but 2 aren't).
Then the way you wrote would be 1) 4x to A, kills A 2) 3x to B, kills B. 3) 2x to C, survives, 4) 1x to D, survives; E is unharmed.
But what might instead happen is 1) 1x to A 2) 1x to A, 1x to B 3) 1x to A (dies), 1x to B, 1x to C; now B is nearest 4) 1x to B (dies), 1x to C, 1x to D, 1x to E (this sequence landed an extra strike worth of damage, on E)

great analysis

This morning I woke up and saw that Valkyrie Connect had given me a notification related to Bergelmir. Here's what it said:
"The new Alter Saga hero's chest gives Vidar's a run for its money. (lenny face) He'll be great in the..."

And then I couldn't read the rest. wink
