Attack routine

• Strike (with flank) -> Hematocritical if crit -> spell, or

• (if hasted) Sure Strike -> Strike (with flank) -> Hematocritical -> spell

Spell is one of:

• Ignition (melee with flank)

• Ignition (ranged due to reach)

• Live Wire

• Electric Arc (1-2 targets)

• Breathe Fire / Fireball

• Blazing Bolt (1-2-3 actions)

• (out of round) Brine Dragon Bile

Spells from slots are at maximum rank -1, so that they can be cycled with Syphon Magic.

sure_strike = xarray.DataArray(
    [False, True, False],
    dims=["Sure Strike"],
    coords={"Sure Strike": ["Normal", "Sure Strike", "Only on melee crit"]},
)

• Dimensions challenge and sure strike represent a what-if analysis. Roll dice only once and compare the results against different situations.

• For AoE spells with a saving throw (Electric Arc, Breathe Fire) roll damage only once, but roll saving throw individually for every target.

• For Blazing Bolt, roll both attack and damage individually for every target.

What are the chances of a critical hit on the initial weapon strike?

Sure Strike
Normal	50.1	25.1	5.0
Sure Strike	75.1	43.8	9.8
Only on melee crit	100.0	100.0	100.0

The conditions of the next spell change depending on the strike and equipment

• If the strike was critical, we can use Hematocritical

• If the weapon was rooting, the target is now Clumsy 1

• If the weapon was a sword, th target is now off-guard even if not flanked
