|A heavy suit of body armour consisting of narrow strips of metal which are attached lengthwise to a thick leather backing. While offering great protection, splint mail is quite difficult to move in without proper training.|
Splint mail is a fairly heavy suit of body armour, providing defense similar to but worse than plate armour. Casters should never use it, and physical fighters should probably upgrade to something better when the opportunity arises. It does provide adequate protection for those who don't quite have the strength to wear plate armour yet.
Splint mail was removed in 0.13, and chain mail was bumped up to 8 base AC to take its place.
