Oh I see. Sweet. Have the HD healing later if she needs it. :) She usually casts her goodberry in the evening.

Tobias had no magic items.

Zean had a magic mace you got from one of the tombs. Once party would move around the dungeon I can make them discover both Zean's corpse with the mace and the new PC created by mathias0077.

For simplicity we could make new PC run loudly upstairs and be another person Tante Lude met before she died last time.

Regarding holy water.
First and most importantly I don't like how holy water works in 5e in combat. Rules say you "in either case, make a ranged attack against a target creature, treating the holy water as an improvised weapon" and I don't believe anyone of you are proficient with improvised weapons or wouldn't get disadvantage for ranged attack when undead is in 5 feet of you...

Second, even if we assume your PC for whatever reasons carry around 250 silver coins (instead of 10 times as little gold), you would still need tools to convert a coin into a powder.
ToA is is cruelly designed to let you not purchase tools and ingredients you happen to need inside tomb of annihilation. I would like to keep that cruelty.

@mathias0077 could you please list your previous PC equipment for other players to loot your ex PC dead body.

Everyone, let's vote on how you want to proceed
