Modeling Clay

Effects

• Has a 50% chance to mimic the effect of a random passive item from the current room’s item pool when entering a room.

Notes

• Modeling Clay can only mimic items that have the "[summonable](/wiki/Item_Tags_summonable "Item Tags summonable")" item tag, the same way (Lemegeton) Lemegeton selects the wisps it summons.
• The item given by Modeling Clay is locked within any given room.
• Items that would give or remove consumables or heart containers will not do so if Modeling Clay mimics them.
• If Isaac holds multiple copies of Modeling Clay, they will all mimic the same item.
  • Note: This will not give multiple copies of the item, Isaac will only receive one copy.

Interactions

• (Chaos) Chaos: Removes the room pool constraint for Modeling Clay's available items.
• (Sacrificial Altar) Sacrificial Altar: If Modeling Clay is currently mimicking a viable familiar, it will also be sacrificed and spawn an additional Devil Room item, but Modeling Clay will not be destroyed.
• (TMTRAINER) TMTRAINER: Modeling Clay cannot copy glitched items; it will do nothing and not have a sprite if it tries to.

If Modeling Clay mimics the following items, they will behave in the following ways:

• (9 Volt) 9 Volt: 1-room charge active items will not recharge over time. Other active items are affected normally.

• (Belly Button) Belly Button / (Mom's Purse) Mom's Purse: Allows Isaac to hold another trinket alongside Modeling Clay if he picks it up while Modeling Clay mimics the item, and he will continue to hold both even after Modeling Clay changes. If Isaac tries to pick up another trinket while he already has two, it will instead be destroyed and he will only be able to hold one trinket again.

  • Isaac can safely exchange cards/pills/trinkets by manually dropping them, at the cost of being unable to hold two.
  • Extra trinkets held this way are susceptible to not working properly, if at all.

• (Black Candle) Black Candle: Does not remove the current floor’s curse.

• (Bloody Lust) Bloody Lust / (Bloody Gust) Bloody Gust / (False PHD) False PHD / (Keeper's Sack) Keeper's Sack / (Rock Bottom) Rock Bottom: Stat boosts will not persist after Modeling Clay changes. If it mimics that item again, it will remember the stat boosts they gave.

• (Blue Map) Blue Map / (The Compass) The Compass / (The Mind) The Mind / (Treasure Map) Treasure Map: Does not reveal rooms on the map.

• (Candy Heart) Candy Heart / (Soul Locket) Soul Locket: Stats granted from picking up hearts will persist after Modeling Clay changes.

• (Cambion Conception) Cambion Conception / (Immaculate Conception) Immaculate Conception: If Isaac can somehow meet the requirements for these items to spawn familiars, the familiars will persist for only one room after Modeling Clay changes.

• (Delirious) Delirious / (Mr. ME!) Mr. ME!: Has no effect, even if Isaac uses his active item.

• (Dog Tooth) Dog Tooth / (Spelunker Hat) Spelunker Hat / (X-Ray Vision) X-Ray Vision / (YO LISTEN!) YO LISTEN!: Will reveal/open neighboring Secret Rooms.

• (False PHD) False PHD / (PHD) PHD: Pills’ effects will be changed, but they will not be identified.

• (GB Bug) GB Bug: The familiar respawns every time the trinket mimics the item.

• (Glitched Crown) Glitched Crown: Items that are spawned while it’s being mimicked will cycle between 5 different items, even after Modeling Clay changes.

• (Isaac's Tomb) Isaac's Tomb / (Voodoo Head) Voodoo Head: If Isaac can enter a trapdoor to the next floor while it’s being mimicked, they will have their normal effects.

  • Other items that activate on floor transition (such as (Dream Catcher) Dream Catcher, (Empty Heart) Empty Heart, or (Lost Soul) Lost Soul) will not work.

• (Little Baggy) Little Baggy / (Polydactyly) Polydactyly / (Starter Deck) Starter Deck: Allows Isaac to hold two cards and/or pills if he picks them up while Modeling Clay mimics the item, and he will continue to hold both even after Modeling Clay changes. If Isaac tries to pick up another card/pill after Modeling Clay changes, the inactive card/pill he was holding will be destroyed and he will only be able to hold one card/pill again.

  • If Isaac goes to a new room while Modeling Clay mimics Starter Deck/Little Baggy, cards/pills in the new room will be converted appropriately.

• (Member Card) Member Card: The special trapdoor will not spawn.

• (Missing No.) Missing No.: Does not reroll items, unless carried to another floor.

• (Sacred Orb) Sacred Orb: Temporary items are affected by Sacred Orb.

• (Sanguine Bond) Sanguine Bond: The unique spikes will not spawn.

• (Schoolbag) Schoolbag: If Isaac picks up another active item while Modeling Clay mimics the item, the other active item is dropped after Modeling Clay changes.

Synergies

• (Golden Trinket) Golden Trinket / (Mom's Box) Mom's Box: Increases the chance of triggering to 100%.
• (Rock Bottom) Rock Bottom: Permanently increases Isaac's stats when it transforms into an item that surpasses Isaac's current stats.
  • This allows the player to enter and exit a room any number of times in order to get as many stats as possible.
