a modified version of the paladin kings addon
lets you see in the Titan bar how many Sacred Candles you got.

in addition, rings and alarm when you are in main city and low on candles

you can adjust the alarm threshold by manually editing first entry in LOCALIZATION.LUA
TITAN_SACREDCANDLESCOUNTER_ALERT = 10;

change 10 in whatever you want. it will ring if below that number

(if i get enuf time, i will do an in-game option)
