Merlin's Tower Ritual

E/F/M:

The length of time required to complete this Ritual is 100 Action Tums (600 minutes or 10 hours), less the caster's STEEP. with a minimum time of five ATs (10 ATs for Partial Practitioners). When activated, Merlin's Tower appears to be nothing other than some prominent natural (or possibly artificial) feature of the surrounding terrain which is above the other features nearby. Thus, in order to succeed the caster must select some outstanding place or thing upon which to center the Casting Typical placement is on a lone hill, huge v., rock sp., boulder of largest proportions, or (at worst) a hillock termite mount. etc. The feature seems unchanged, but around it the Formula shapes an invisible structure as strong as tonne into which the caster can go as a refuge. A dozen or more can be housed in this tower. All inside are invisible, and no sound emanates from the area Inside, the tower seems to be made of stone, and has a diameter of 20 to 50 feet. depending on the size of the prominent object the Casting is centered upon. It also has a winding stair which leads to the story(s) above and to the tower's flat roof. The tower will have two stories, plus one additional story for every 10 feet of height of the prominent feature Note that even when observing the surrounding terrain from the roof. occupants of Merlin's Tower are not visible to normal sight Tower strength is equal to stone of a thickness and hardness commensurate with the feature selected. Rock equals 10-foot-thick walls of the sort of stone concerned. Hills are equal to half that thickness in limestone of a hardness commensurate with the size or steepness of the t. Trees equal one to three feet of hard to semi-soft sandstone. A hillock in a swamp, or a termite mound on a plane will produce only a 20 foot high tower with walls one foot thick whose hardness equals one foot of soft sandstone! However, the caster can expend addition. Heka to thicken and harden the protection. Each additional 25 Heka points adds one foot thickness equivalent while hardness can be Increased by expending 50 per degree. Stone hardness degrees are: sedimentary?soft semi-soft. hard then igneous?soft, semi-soft. hard.
