Percussions skill
The Percussions skill is trained by playing percussion-type musical instruments. They were created by the god Idon.
This skill is learned by playing upon percussion instruments, ie: tambourines, bones and drums.
Some instruments require tools to be played, ie: bodhrans require tippers, drums require sticks.
Bards use percussion instruments to play certain enchantes and their skill with the instrument can affect their ability to perform the enchante properly.
Percussion instruments may also be played just to be played, and there are several mood and tone options available. Bards have extra options available to them for playing instruments that are not available to other guilds.
Bards and non-Bards of sufficient Percussions skill can increase the spirit regeneration of all those in the room by flawlessly playing a minuet (or higher) on any percussion instrument.
Clerics and Paladins can gain devotion or soul state respectively by playing a psalm or hymn for an Immortal in a holy place.
Instruments
Percussion instruments are played by striking, scraping or shaking them. Some require special tools such as tippers to play, while others are simple enough to play in one hand. Similarly, some have skins that require tuning and can be broken, necessitating replacement before playing again.
