You touch one willing creature. Once before the spell ends, the target can roll a d4 and add the number rolled to one ability check of its choice. It can roll the die before or after making the ability check. The spell then ends.
The wood of a club or quarterstaff you are holding is imbued with nature's power. For the duration, you can use your spellcasting ability instead of Strength for the attack and damage rolls of melee attacks using that weapon, and the weapon's damage die becomes a d8. The weapon also becomes magical, if it isn't already. The spell ends if you cast it again or if you let go of the weapon.
Make a melee spell attack against a creature you can reach. On a hit, the target takes 3d10 necrotic damage.
At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d10 for each slot level above 1st.
A creature you touch becomes invisible until the spell ends. Anything the target is wearing or carrying is invisible as long as it is on the target's person. The spell ends for a target that attacks or casts a spell.
At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, you can target one additional creature for each slot level above 2nd.
Your exposure to the Shadowfell's magic has changed you, granting you the following benefits:
Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
You learn the Invisibility spell and one 1st-level spell of your choice. The 1st-level spell must be from the Illusion or Necromancy school of magic. You can cast each of these spells without expending a spell slot. Once you cast either of these spells in this way, you can't cast that spell in this way again until you finish a long rest. You can also cast these spells using spell slots you have of the appropriate level. The spells' spellcasting ability is the ability increased by this feat.
