Banish (ritual)

found on page 160 of GURPS Thaumatology in 4e, is based on ritual of the same name from GURPS Spirits and GURPS Voodoo
==3e to 4e change==
In both cases a combination of mental and physical characteristics of the target were taken into the success rate but in different ways.
3e Spirits pg 105 (not to be confused with the spell on S106) as well as HB127 resisted and did not specify anything special, which would mean a default to Will. However it applied a "penalty equal to the total ST and HT of the spirit".
4e's Thaumatology removed ST from the equation: "additional skill penalty or energy cost equal to the target spirit’s HT"
4e also removed the 3e caveat of spirits dying if the damage roll exceeds HT (even if it doesn't reduce HP to zero due to Extra HP .. at the time HP was based on HT not ST)
Probably the reason for this was to avoid sort of a double-dipping effect in that high-ST (by providing more HP in 4e, unless bought down) usually makes one more able to survive this, so giving it an added benefit in also penalizing the ritual to lessen damage is like giving DR too.
