Re: Summonmancer question
Ahh... you're right, you technically can, but it's a risky and unadvisable endeavor. Without getting into too much detail, if you die and end up with split corpses, doing that can cause you to lose a chunk of your gear.
If you're playing hardcore, that obviously doesn't matter. If you're not and are sure you want to go that route, I'd just look through the set and unique items on Arreat Summit for cheap things with +strength.
Edit: I'm not sure if this is information you already know, but here's a more complete copy and paste from Battle.net:
There are two glitches commonly referred to as the "strength bug".
The first one is rather harmless. When you don't have the base stats needed to equip an item, other players will not see the item, even though they are there and take full effect. This can be quite humorous when a "naked" barbarian stands in the middle of a monster pack and "punches" them to death. Another example is when Amazons throw Lightning Furies with their bare hands. This is not a hack, merely a display issue.
The second glitch is somewhat more serious. This is when you do not have the base OR end stats to equip an item that has +stats, making the item sustain itself. Example:
Your character has 150 strength after all gear, excluding the shield. You want to equip a Stormshield. In order to reach the 156 strength required, you put a charm in your inventory that gives you +6 to strength, giving you 156 strength, enough for Monarchs. You can now equip the shield. This brings your total strength to 186 with the strength bonus from the Stormshield. Now this is where the glitch comes is: You can now remove the charm from your inventory, but the +strength from the shield will still be enough to equip the shield. The shield is now, in effect, supporting itself. This is an extremely dangerous practise, because if you die, you will not be able to reequip all of your gear, so if you die again, you will be left with multiple corpses. Since only one corpse (the one with the most valuable items... in gold) will be transferred to the next game you enter, abusing this glitch to save stat points is an excellent way to lose your gear. Excepted from this are hardcore players, who lose all their gear anyway when they die.
On a related note, using +stats from items to equip other items is not a "glitch". This is perfectly natural. However, doing this can sometimes result in needing to click your corpse multiple times to get all your gear back, and having to pick up and reequip items when you enter a game.
