Summoning chamber

Summoning chambers are special areas which are sensitive to the piercing of the veil, increasing the ease with which sorcerers use Minor Summoning(725). Casting within a chamber will add a flat 600 sec to the duration of Minor Summoning (725), and provide 25 'phantom' ranks of Sorcerous Lore, Demonology for the purposes of calculating the success of the summoning only. In addition, using the vakra rune to refresh the duration while in a chamber increases the duration by an additional ten minutes.
