Second, use rentals to get your equipment or buy a compound bow and/or a katana (if you need to save up for the katana, use rentals).
Third, there are few strategies in which I'd recommend the use of multiple attacking minions (and in those few examples, one attacking minion would still be quite effective), using three minions to attack is not stronger than using one minion (either supported by enchanters or without extra minions to dilute EXP). It also has the downside of leaving you particularly vulnerable to AMF and EC, not to mention that your tank will be very weak against other tanks (low DX).
I don't intend for this to be sounding like I think you've done a poor job of creating a strategy for yourself, but instead that you've made a lot of the mistakes most newbies make (I made many myself).
Here's a few game strategies people have put in the wiki, I'd suggest one of these:
Grant's Strategy
Stryfe's Strategy
MilkWolf's Strategy
Pyro's Strategy
Rommel's Strategy
G-Wolf's Strategy
Let me add that what these guys have put as their suggestions only needs to be the basic structure of your character, you don't have to do exactly as they say but instead start with their suggested strategies and edit it as you find changes are needed. It just means that your strategy is based on well proven tactics.
