Accursed Footwear

Each pair of the cursed shoes described below cannot be removed once worn, at least without using magic (eg. Remove Curse) or a hacksaw.

1. The Clog of Transformation. Each day, the victim becomes more and more... woody, losing one point of STR, DEX or CON, determined randomly. Once any stat reaches 2 or less, the victim starts to sprout twigs and grow leaves. Once any of the stats reaches zero, the victim is fully transformed into a small tree.
2. The Hungry Boots. The shoes have delaminated soles, giving them a hungry look. If one looks closer, he/she can notice multitude of small but razor-sharp teeth, adorning the shoes' "mouths". The Hungry Boots deal 1d4+1 additional kick damage as bite but must taste blood every day or they will drain 1 HP from their wearer each day.
3. Demonic Ballet Shoes. When worn they allow to move without making a sound, even during jumping or kicking. Unfortunately, the wearer cannot move in any manner other than dance. For each character with DEX less than 16 it means -1 to all to-hit rolls and +1 to AC. This penalty is doubled if DEX is lower than 8. Of course, the dancing movement can cause many other issues - just imagine an audience with a king...
4. Boots of Inversion. Once worn, they immediately flip the gravity for the wearer, slamming him/her onto the ceiling (fall damage may apply). Too bad if they were worn under a sky - it will take about twenty to thirty minutes for the victim to reach the escape velocity.
   
5. The Black Fins. The swimming fins made of black studded leather. They allow to breathe water and swim and dive effortlessly. Unfortunately, their wearer is no longer able to walk (treat him/her as having DEX of 1 on land)... or breathe air.
6. Assassin's High Heels. The legend says that they once belonged to a dwarven assassin Ho'dak the Dreadful. They grant immunity to all poisons and venoms and can be used as a +3 kicking weapon with a magical poison damage (save or die). Unfortunately, the footwear's curse manifest in a peculiar way - every sentient being is immediately aware of the wearer's presence (and the fact that he/she is wearing a strangely looking high heels) - even being invisible makes the surrounding beings suspicious and tense.
