The Paladin
Spellbook - Defensive Spells
The shield works by simply absorbing a considerable amount of damage inflicted upon the recipient. When your fa.s.d.s skills goes high enough, it will reach its maximum absorbing ability which is 75%. You can have an idea of how good your shield is by checking the message it gives when you are hit. The rating of the damage it absorbs will vary from small or good reaching gradually huge and enormous. Enormous is the final and highest rating for your shield's absorbance.
The shield will not wear off with time but with the damage it absorbs. There is a certain total amount of damage it can absorb and when it reaches it, it will leave you defensless. Fortunately, if you are using ansi color for mudding you will be able to get an idea of how close your shield is to wear off by the color of the message it gives when absorbing damage. This will vary from blue (a new shield) to green,yellow and finally red right before wearing off completely. You will be given a message "Your shield of faith is weakening" before it reaches the red level. Your shield will absorb 75% of the damage at all times, however close to leaving you it is.
When fighting good aligned NPCs or players, the absorbing ability of the Shield of Faith is merely 55%. It will protect you by absorbing 75% of the damage inflicted upon you only when you fight evil aligned targets.
