When and Where Should I Cast Arms of Hadar?

Arms of Hadar is a spell best used in low-level fights. Though its effect is beneficial, it lacks the innate firepower of higher-level spells. It will usually fall off in favor of more efficient spells for the Warlock’s limited spell slot pool.

It will see the best use from the Pact of the Blade Warlocks, who will be up in the front lines of combat with their pact weapon. It has no innate ability to protect an ally from its effect, and players should be mindful of their positioning when using it.

Why Should I Take Arms of Hadar?

At low levels, Arms of Hadar is quite helpful. It provides decent damage and a little bit of lockdown to the caster for a low-level spell. It can be utilized effectively to get the Warlock out of a scary situation.

However, its low damage dice value and effect are simply not worth upcasting it at higher levels. So it’s better slotted out for a more efficient spell.
