Does Gentle Repose extend the time limit for casting Revivify?

The spell revivify returns a creature to life “that has died within the last minute.” [PHB 272]

The spell gentle repose “effectively extends the time limit on raising the target from the dead, since days spent under the influence of this spell don’t count against the time limit of spells such as raise dead.” [PHB 245]

My question is whether revivify is one of the “spells such as raise dead” for which gentle repose “effectively extends the time limit”, taking into account the fact that revivify is two spell levels below raise dead and its default “time limit” is not measured in days (it is in fact 1/1440th of a single day).

If I have a single diamond worth more than 300 gp, does Revivify consume the whole diamond?

Thanks to a heist of mixed success, I have in my possession a single diamond worth roughly 550 gold pieces. If I use this diamond to cast Revivify, will casting the spell consume the whole diamond? I know that I could also use the diamond to cast Raise Dead, but that comes with drawbacks and is a bit overkill if the target has been dead for less than 10 rounds.

In my understanding, the worth of diamonds IRL comes from their ability to refract light, so even if Revivify doesn’t consume the entire diamond, would the remaining piece of rock be of significantly less value?

Will revivify work on a creature killed by Extract Brain?

Mind flayers (Monster Manual, p. 222) have the Extract Brain action:

Extract Brain. Melee Weapon Attack: +7 to hit, reach 5 ft., one incapacitated humanoid grappled by the mind flayer. Hit: The target takes 55 (10d10) piercing damage. If this damage reduces the target to 0 hit points, the mind flayer kills the target by extracting and devouring its brain.

If a mind flayer kills a creature with their Extract Brain action, will revivify return the creature to life as normal?

Can an Adventurers League character or party reimburse a PC for casting revivify?


The Situation

One PC just died. Fortunately, another PC is a cleric that has revivify prepared, an unused 3rd-level spell slot, and 300gp of diamonds they purchased before the session. They cast revivify and bring the dead PC back. The newly-revived PC is grateful and wants to reimburse the cleric, who just spent four sessions worth of gold.

The Problem

According to the Adventurers League Player’s Guide (ALPG):

Rewards and equipment can’t be given to another character, except as follows:

  • You may lend equipment and magic items to other characters at your table but must return it at the end of the session unless consumed (like a potion).

    […]

  • Characters may choose to divide the cost of NPC spellcasting services obtained during an adventure.

ALPG v8.2, page 3

The revived PC cannot permanently (nor temporarily, I believe) give the cleric PC 300gp. The party also can’t do so. Only NPC spellcasting services can be divided. They also can’t buy 300gp of diamonds later and give them permanently to the cleric. The PC could probably lend the cleric diamonds to cast the spell, assuming they count as equipment instead of rewards.

Must every PC pre-purchase 300gp of diamonds or a scroll of revivify, just so their clerics don’t go broke? What if the PC’s death wasn’t their fault, so the party wants to split the cost? One final wrinkle – AL tables may have different players each week. An answer that works in a convention one-shot is better than one that only works in a 20-week hardcover.
