Utilization you ask....
As with any real multiplayer roleplay game, you have complete freedom of creativity and possibility, limited only by setting of game, in this case MD realm. With such freedom comes system's inability to make decisions in conflicting actions of interaction among players. in other words system can't decide anything (nor it exists) rather, social environment (community of other players that are present at the place of action happening) decides the outcome...
Basically if you are to hit somebody on the head with a bottle you must make it believable that you have the means and ability to do it on your target for all the present observers and action should be accepted or refused/countered in same manner by the victim subject so to speak.
Now all those RP commodities such as items, avatars, spells, tags, "character-establishment" and such come into play because they reinforce that said "reality". As a follow up to above example, if you have avy that looks aggressive, item called head cracking bottle and a tag named head smasher; the above exemplary action would be very likely to be accepted by surrounding players. On other hand if you always force something to happen the way you want it with no regards to your and other player's rp "resources", then you are basically god modding.
