Spell Shift (1/Day). When the skeleton casts a spell that deals acid, cold, fire or lightning damage, it can use a bonus action to cause the spell to deal a different one of those damage types.
Spell Weave (1/Day). The skeleton can cast one 2nd level or lower abjuration, evocation or necromancy spell, that has been woven into it. The chosen spell must only affect a single target and must have a casting time of 1 action.

Teleport. The skeleton magically teleports, along with any equipment it is wearing or carrying, up to 20 feet to an unoccupied space it can see.
Skeleton arcana are easily distinguishable from their lesser counterparts, due to the metallic bangles and other enchanted rings that adorn their frame, the hallmark being a somewhat malleable sphere of energy that sits inside the undead's chest that gives its frame an eerily set glow when at rest.
Deathly Lore. Skeleton arcana are the brainchild of a long dead archmage from the lands of Amesha. They were created to be more of a supplementary note to her family's standing guard regiment and were used as a means to back up conventional soldiers with a reliable and self sufficient support. The project was such a success that the wizard was promoted to the rank of archmage before her first evaluation was even complete. Only when more wizards began to make their own versions of this undead, did the council actually step in and force a resolution.
Creating an Arcana. Skeleton arcana are created much the same way as any other skeleton, however the creator is required to use several materials to enhance the undead's frame, making it capable of containing the energies used in its attacks. All of this costs around 1,500 gp and the original caster must use eight hours of work to create the magical anchors and attach them to the skeleton's body. If the caster is proficient with jewelers' tools, it can cut this time in half and lessen the expense to only 1,200 gp.
Undead Nature. A skeleton arcana doesn't require air, food, drink, or sleep.
