Effect: The caster flicks their hand as if waving away a fly, summoning the magic circle. Unleashes a relentless barrage of acidic projectiles upon the enemy. Each projectile contains a concentrated acid that eats away at the target. The acid's corrosive nature weakens the target's defenses, leaving them vulnerable to subsequent attacks. D-buff to Endurance.

Caustic salve: Is this a single target or an AoE heal? If single you need to add projectile size, and which stat it heals constitution or endurance. If AoE you need to put the size of the healing and the places of circles. "It neutralizes toxins and cleanses the body of harmful substances. The acidic nature of the elixir also enables it to cauterize wounds, preventing excessive bleeding and providing immediate relief to the recipient." You need to remove this part as it reads as if it stops damage over time effects which it wouldn't.

Burn coat: You need to put the range of the spell, as well as spell circle as well as what stat you are buffing for them. "The acid infuses their attacks with corrosive properties, enabling them to cut through defenses and cause additional damage upon impact." <--- This needs to be changed as it reads as if you buffing them gives acid passive which it wouldn't

Corrode momentum: you need to put in the size of the defensive spell as well or if it is a body shield that it says that as well the amount of damage it blocks for. as well as spell circle.

Corrode shell: you need to put what stat this is debuffing, it can not "erode armor". as well as spell circle
