In Flyff,to pierce a suit you will need a suit and a moonstone. I reccomend using a scroll of Gprotect as it will prevent you losing the armor if the piercing fails.

You are able to get 4 slots after piercing and in these you can place cards.Cards add 2% 3% 4% or 7% of the following bonuses and the higher the % the more expensive.

Volcano cards add HP these are the most useful to a full int or low sta build as they can give you the hp boost you need to take a hit from an aggro and with a +10 set and 4 7% volcano cards you'll have almost 50% extra hp. and with a gstick and the level 60 set you can get up to 78% more hp.

Earthquake Cards add Defence, These are the best for survival as the defence gain is minimal for some sets as 7% of a low number doesn't make for much of an increase.

Ocean cards add MP These are best for CW RM's who may well have enough hp without hp piercings although i'd still reccomend volcanoes for all builds.

Vacuum cards add FP. Avoid them. 'nuff said.

Lightning cards add Attack. Again, do not use them.

Hope that help.Give credit to Divirgupta
