Waaagh Chanta's are found all over the world usually parading alongside large warbond to empower their warriors and spell fear into anything that might cross there path. They are however kept at a reasonable distance from the troops for some weird reason.

Big WAAAGH Energy

Starting when you choose this Subclass at 3rd level, your spellcasting can unleash surges of untamed magic. Whenever you cast a leveled spell of 1st level or higher or when you give out a bardic inspiration, the DM can have you roll a d20 immediately afterwards. If you roll a 1 or 20, roll on the Wild Magic Surge table to create a magical effect. If that effect is a spell, and if it normally requires concentration, it doesn’t require concentration in this case; the spell lasts for its full duration.

SMASHIN' EADZ

At 3rd lvl your bardic inspiration can also be used for damage rolls.

WAAAGH ON!

At 6th lvl when you or an ally within 30ft of you takes damage you can use a reaction and spend 1 bardic inspiration to half the damage taken of that attack. You can use this ability aslong as you have bardic inspiration points available.
