The potential of mortar totem as a weapon swap.

Mortar Totem is a very powerful ability both as a main damage skill and a very smooth utility/support skill.

You can socket multiple grenade skills into the totem and grenades with multiple uses start with a full clip. If your build has any investment in attack speed, a Totem with Flash Grenade and Voltaic Grenade, urgent totems 3, and payload. Using a basic phys damage crossbow on swap will give you a 1 button per 8 second aoe stun and electrocute dispenser.

You don't even need to be invested into grenade passives if you are too far away but if you aren't you can you use weapon swap passives on stun and electrocute/immobilization scaling. If you can afford to perfect jewllers it you can even convert flash grenade to pin.

Overall, it is a very easy way to access CC and there is an underrated aspect to using totems to block projectiles or certain boss moves.

For example, and I know there are many who are struggling with it, the Prince Boss's 1 shot move can be blocked by summoning a totem in front of him while he is dashing.

I hope this helps your build.
