Generally if you haven't been granted permission to do something which is very powerful and automatically gives you the upper hand, please clear it first!!!
Certain little spells are available to everyone, for example:
TRIP (trips a person or animal. Generally harmless aside from humiliation) BREAK (will break small objects such as weak locks, glass, jewellery, toys) STOP (will stop a small object from hitting the floor in mid air) GO (The counterspell for the STOP spell - you will not be able to move the object from its place unless you spellcast GO)
Theseare all generally harmless. However, if you are a mage you may use greater spells, or if you have been granted a greater spell by a mage. Other wise clear spells, please!
Yes - tat was a good point. I think you know what your character is and isn't capable of, and so far I don't think you've used any overly powerful spells!!!
