Or better worded as:
What is the max Health and Mana base, that gets used to calculate the benefit provided by the Mayan, Ceylonese and Logosian bracelet artefacts.
Does it stack with benefits from CON artefacts and/or runes?
i.e.
A CON of 12 gives a Level 80 Character a max Health and Mana of 3500
Thus a Mayan bracelet will push this to 3500 + 175 = 3675, where 175 is 5% of the max 3500
A CON of 13, through the use of an artefact or rune, pushes the max to: 3740
Does this mean that the same Mayan bracelet now causes a max of:
(a) 3740 + 187 = 3927
Where 187 is 5% of the new max after CON benifits
Or
(b) 3740 + 175 = 3915
Where 175 is the 5% from the max calculated with base CON.

As for +con vs bracelet: For the level 1 artefacts, a con belt and a bracelet are pretty similar (ignoring that the belt also boosts endurance and the bracelet also boosts mana). The lower your con, the better the belt will be. Assuming you only care about health, I'd probably go with the belt if you have less than 14 con, otherwise the bracelet will be 50 credits cheaper for about the same (or more, at 17+ con) benefit. For level 2/3, the bracelets are so much cheaper that you probably shouldn't get the belt first unless you need the endurance or you only have 12 or less con.
