Don't worry, I did this for a chaos character I tried out in the past. Dual Shotels, Large Leather Shield, and a Pike. Was fun.
Parrying with Shotels? It is not like shields; If the enemy is about to hit you, like actually about to hit you... parry with shotel. Good for those instant parries, I have found while playing.
As for parrying Spears, the same method... only... closer.
