Enchantments to boost your stats

There are well over 100 enchantments in the game, but they follow some basic patterns that are worth knowing. In particular, the most popular and common style enchantments simply add a stat bonus to an item that you wear. In fact, about half of the known enchantments are of this type.
Stat bonuses can not be applied to all items. In particular, they are limited to boots, bracers, cloaks, gloves, shields, and weapons.
Below, I summarize these common stat boosts in two tables.The first table organizes them by stat, so you can see what to pursue to boost your favorite ability.

Agility	Boots, Gloves	+1, +3, +5, +7
	Cloak	+1, +3
	Bracer	+1
	Weapon	+15
Intellect	Bracer	+5, +7
	Weapon	+22
	2H Weapon	+3, +9
Spirit	Bracer, Shield	+1, +3, +5, +7, +9
	Boots	+3, +5
	Weapon	+20
	2H Weapon	+3, +9
Stamina	Boots, Shield	+1, +3, +5, +7
	Bracer	+1, +3, +5, +7, +9
Strength	Gloves	+5, +7
	Bracer	+1, +3, +5, +7, +9
	Strength	+15

Table 1 ' Common stat enchantments, by ability This second table has the same information, but this time tabulated by item.The idea is that when you pick up a good item that you know you want to hold on to for a while, here is an easy view of stat buffs available for that item:

Boots	Agility, Stamina	+1, +3, +5, +7
	Spirit	+3, +5
Bracer	Spirit, Stamina, Strength	+1, +3, +5, +7, +9
	Agility	+1
	Intellect	+5, +7
Cloak	Agility	+1, +3
Gloves	Agility	+1, +3, +5, +7
	Strength	+5, +7
Shield	Spirit	+1, +3, +5, +7, +9
	Stamina	+1, +3, +5, +7
Weapon	Agility, Strength	+15
	Intellect	+22
	Spirit	+20
2H Weapon	Spirit, Intellect	+3, +9

Table 2 ' Common stat enchantments, by item
The costs of the above enchants are, of course, higher the better they are.Estimated mats costs for all of them are in the summary table below.However, here are some useful guidelines:
As with a lot of things in this game, the prices accelerate geometrically (that means 'fast') for each step in improvement.
End-game enchants (the highest of any item/stat combo) are typically extra expensive. There are two notable exceptions: +9 spirit to bracers and +7 strength to boots, both of which are surprisingly inexpensive.
The high-end weapon enchants (all above +9) are very difficult for an enchantress to learn, and have mats that are very expensive. You should expect to pay 100-250G for them (each!).
"Weapons" means One-Handed Axes, Two-Handed Axes, One-Handed Maces, Two-Handed Maces, Polearms, One-Handed Swords, Two-Handed Swords, Staves, Fist Weapons, Daggers, Spears
