Agnes' Ironflesh Infusion

“Is it healthy? No. Is it convenient? Also no. Is it comfortable? Absolutely not. But it will definitely keep you safe. If it fails to keep you alive, please contact me for a full reimbursement.”  

  - Excerpt from the label of one of Agnes Rosenthal’s potions

Drinking from a special concoction, you temporarily turn the target’s skin to heavy metal. The target of the spell gains the following effects:

• The target gains resistance to magical bludgeoning, piercing and slashing damage, as well as Cold damage, Fire damage, Necrotic damage, and Poison damage. However, they also become vulnerable to Acid damage and Lightning damage.
• The target’s speed is reduced to 10 feet and cannot be increased by any means, and they must make a Strength check to rise from a Prone position. However, they also gain advantage on Strength-based ability checks and saving throws, and cannot be involuntarily moved outside of teleportation.
• The target’s Armor Class increases by 2.
