Depending on what deal you made with my lord, he will grand you some new powers that only you can use them.

Everybody gets the Soul Snatcher, with that every time a creature dies from your hands or your allies within 60ft from you, I can absorb a part of his soul. Of course it has to have a soul, don't try to use that to undead or constructs you stupid little goblin.

For you especially, so that you are not that useless, my lord will give you:

• Silver Tongue Enchantment: Once per long rest you can use your Silver Tongue to any skill check you want.

• Helping Hand: If an enemy is almost dead and an ally of yours is going to attack him, you can use your reaction to "lend a hand" to your ally. I will appear as a spectral hand and deal an additional [roll]1d6[/roll] necrotic damage. If the creature dies by that hit, I will absorb all of his soul (that counts as 2).

Oh... I almost forgot to mention that I will enhance you spells, not all of them of course, only the ones my lord gives you. So your warlock spells have +1 to attack rolls and +1 to DC saving throws.

Ok that's all for now, did you understand, you stupid little mortal goblin???

Notes: You need to be accepted and form a pact with its lord the Archlich Zalthar the Cursed Wyrm of the Grave
