local statictimer = FALSE -- Options: TRUE or FALSE, if TRUE death timer will be the same for all creatures, if FALSE timer will be target's current hp divided by variabletimerbase --
local timersec = 30 -- Time in seconds before killing target, Only works if statictimer = TRUE --
local variabletimerbase = 600 -- if statictimer = FALSE death timer will be equal to target's current hp divided by this variable value --
local workonplayers = FALSE -- Options: TRUE or FALSE, if FALSE this spell won't work on players, else it will --
local dispelable = TRUE -- Options: TRUE or FALSE, if true the curse can be stopped ---
