Alternate Limitations

[Eodin]

What would be the cost of two alternative limitations?
Example: Spell of Woodthrust: RKA 1d6; Incantations, Gestures, Requires Magic Roll, and
either OAF (Wooden staff; -1) OR Extra End (x3 END; -?) and
either Extra Time (Full Phase; -1/2) OR Concentration (x1/2DCV; -1/2).

In other words, the caster has two variables:
One - if he has his staff, he casts it at normal END, but without the staff it's at x3 END. In other words, Variable Lim with two fixed possiblities?
Two - if he takes the full phase to cast the spell, he's at normal CV, but if he wants a half-phase, he has to concentrate. In other words, Variable Lim with two fixed possiblities?

So are those really variations of Variable Limit, or are they a limited limitaion, and what would the 5E values of those 2 lims be?

For the Increased Endurance Cost, look at the rules on the bottom right of 5E 185 (and the errata for same) -- the extra END cost would only apply when he's sans staff, so the Limitation is worth less.

For the Extra Time and Concentration, look into Variable Limitation.
