Sorcerer/Warlock/Witch/Wizard Level 1 (Transmutation)
With a guttural incantation and a cruel hand gesture, the spell caster causes razor sharp thorns to burst out of the flesh of one living, non-plant creature per level.
The thorns inflict 1d4 points of damage per caster level and targets have disadvantage on all rolls until the thorns are removed – which deals another 2d4 points of damage. If a creature succeeds a saving throw versus magic, the damage is halved and the thorns wither away on their own at the start of the next round.
Option miscast table for LotFP (roll 1d12):
1 – Thorny vines erupt from the ground beneath the caster’s feet, immobilizing them in an expanding briar patch that grows 5 feet per round in all directions for a number of rounds per caster level.
2 – The caster begins bleeding profusely from their nose, ears, and tear ducts, suffering 1d4 damage directly to their Constitution score. They’ll continue to bleed, losing another point of Constitution each round until they succeed a saving throw versus magic.
3 – The caster’s skin permanently becomes rough and fibrous, like the outside of a creeper vine. They lose 2 points of Charisma, but they gain a +2 bonus to their unarmored Armor Class. However, they can now only derive sustenance from the blood of their own species.
4 – The caster feels excruciating pain in their eyes; 1d4-1 rounds later, their eyes swell and burst into crimson rose blossoms that smell like fresh blood. The blooms (and their scent) last for 2d4-1 days then wither away, revealing new eyes with crimson irises. From now on, the caster has advantage on Perception checks to find and follow freshly spilled blood.
5 – After 1d4-1 rounds, any creature with hit dice less than the caster’s level that failed its saving throw versus magic dies as its flesh sloughs off revealing a vine-entwined skeleton that is hostile to all living creatures.
6 – After 1d4-1 rounds, the caster collapses, wracked with pain as a parasitic vine burrows through their body. At the start of each of their turns, the caster must make a Constitution-based saving throw. If they roll three successes before they get three failures, the caster bonds with vine, gaining a extendable thorny tendril that can attack like a whip. If the caster generates three failed saving throws first, the vine begins consuming them from the inside. Every 24 hours, the caster loses 1d4 Constitution; at 0 Constitution, a mature vine creature with hit dice equal to the caster’s level bursts out.
