does a short rest restore spell slots: The Best Warlock Spells By Level in D&D 5e. Baldur's Gate 3: How to rest | Rock Paper Shotgun. Warlock 5e: DnD 5th Edition Class Guide - RPGBOT. Resources - bg3.wiki.
The warlock gets few spell
slots, but they refresh every short rest and scale to the highest available level.
Level 1
Spell Slots → 38% * If you have max Spell Slots (4), you will recover 1
slot at first Short Rest, and 2
more slots at second Short Rest. 3 Spell
Slots in total.
Equally as important though, the rod also gives you the ability to regain a spell slot as an action which, funnily enough, almost doubles your available spellcasting slots per every short rest.
You can also fill up your Spell Slots via short rest, so after every fight make sure to short rest to keep this build having the spell slot fuel it needs.
