Dwarf (Mark of Warding)

Int +1

When you make an Intelligence (Investigation) check or an ability check using thieves' tools, you can roll a d4 and add the number rolled to the ability check.

You can cast the alarm and mage armor spells with this trait. Starting at 3rd level, you can also cast the arcane lock spell with it. Once you cast any of these spells with this trait, you can't cast that spell with it again until you finish a long rest. Intelligence is your spellcasting ability for these spells, and you don't need material components for them when you cast them with this trait.

If you have the Spellcasting or the Pact Magic class feature, the spells on the Mark of Warding Spells table are added to the spell list of your spellcasting class.
1st - alarm, armor of Agathys
2nd - arcane lock, knock
3rd - glyph of warding, magic circle
4th - Leomund's secret chest, Mordenkainen's faithful hound
5th - antilife shell
