Buying Equipment[]
Equipment is recruited at various places around MagicDuel where the only requirement to buy it is value points. Higher level armour is only limited by your value points, so to get better armour you need to gain more pernament or temporary value points
Recruiting and Upgrading Creatures[]
When recruiting and upgrading creatures there is normally a cost of value points.
Massively Negative Value Points[]
Some rituals will product massively negative Value points. You can typically get 2-3 Million negative Value points. This can be annoying if you wish to recruit or upgrade creatures, or buy Equipment as you wont be able to until you get back into positive Value Points.
