From that same castersrealm snapshot. This is talking about impart strength. The same mechanics would apply. See how it mentions giving your whole party the effect and then cancelling it? It mentions 1. the recourse, 2. how the spell isn't gone from party members when it's removed from the caster, 3. how it can be clicked off the necro.

THIS SPELL IS GREAT, By Azrel darkelf necromancer e'ci (1/28/2001)
you can give your whole party +str and then just left click the icon that is on your "effects" stack to turn it off and your party members still gain the bonus (it does override several str buffs cast on you, so just cast this on your party before they buff you)
SLIGHT BUG..., By Gnish (1/28/2001)
This spell will take 10 STR from you and give to another. Well, they fail to mention that it takes 10 from BASE STR without any buff spells on you. So, if your buffed STR (with magic buffs, not items) is 70, but normal STR is 60, then casting this spell will leave you with 50 STR. This is easily changed by casting Siphon Strength on your next target and then you'll be right back up to 70. A beneficial bug, is that you can cast this spell on multiple recipients
