With the poison blade, it would not simply add a damage-over-time status effect. The emphasis would be on other status effects such as slowness, weakness, and disorientation. In the case of the inventory-limited variety, the death would not be caused by DOT, but by a separate meter ticking down.

Soulbind wouldn't do DOT either; the sap in question just refers to the fact that you would gain health and mana from killing people, implying that you are sapping it from them.

Goddamn auto-aim. Ruins everything. v_v

In any case, Steel Spirit gives the projectile itself a homing ability, rather than simply snapping the reticule to the target.
