u mean router ip? that ip is given from the internet provider and i doubt it will be the same.. usually to have a static ip u need to pay an extra to your internet provider.. u can use though instead of an ip a dns.. which are free if you want u can search in google for no-ip.. on thier website u can download a free app which connects to thier database and updates every x minutes your ip to a dns like myserver.home.diz
as for the gmflamefield u have to do a few things..
open the enterpise manager and open tbl_magic.. create a new magic called GmFlameField but be sure that the FLD_ID is = to the last id +1.. in my case if i would want to create one i would put it after poisoncloud which has id 55 so gmflamefield would have id 56.. then the FLD_MIMICID must be = to the FLD_MIMICID of the original FlameField which is 45.. then put all the same values as flamefield in the other fields.. to power the spell up put 20000 in fld_power and 300000 in fld_maxpower..
as for the tbl_stditems it will be enought copying the same values of the original flamefield book execpt the fact that u will need to rename it to gmflamefield and change the id..
