[2.5.16] Soul Reaper

[Hubaris]

I pretty sure the only hero with a "kill command" is legionare

Incorrect.

Withering Presence:

<onframe>
        <setvar0 a="target_maxhealth" b="0.004,0.006,0.008,.01" op="mult" />
        <setvar1 a="var0" b="-1" op="mult" />
        <setvar2 a="var1" b="frametime" op="mult" />
        <changehealth a="var2" />
        <compare a="target_health" b="0.3" op="lt">
            <kill target="target_entity" />
        </compare>
    </onframe>

If they changed the b value from 0.3 to 1 or 2, it can be a very useful buff to him; subtle but useful.

EDIT: So YES he does have a 'kill' command on his aura. The problem can lie in regeneration.
