Having studied Hoyles teachings, you've developed a deeper understanding of his tricks and rules behind his spellcasting art. This has made it easier for you to wield your hexes

At 1st level, your ability to cast spells is better than your average Huckster.
You gain a +1 bonus to Huckster casting checks. This increases to +2 at 10th level and +3 at 17th.

At 6th level, when you roll a 1 on a casting check, you may reroll the check. You must use the new result.
You can do this a number of times equal to half your proficiency bonus per long rest.

At 14th level, your understanding of how to avoid the negative sides of spell Slingin' allows you to sometimes avoid the backlash when critically failing when casting.

If you roll a 1 when casting a spell, roll a D6, if you roll a 1,2 or 3, the spell fails as normal, but you take no backlash. If you roll a 4,5 or 6, you take backlash as normal.

At 18th level, whenever you make a Huckster casting check, you may treat a roll of 9 or under as a 10.
