I tried to figure out a versatile grimoire for building stuff like town houses, walls, castles, towers w/ Rego magic. I would like to receive some feedback and ideas to properly design and fine tune the following spells. Please note that my magus knew ReVi spells for elongate the duration of spell, that's why I use Moemntary or Diameter as Duration. I tried to crunch the numbers in HoH:S Craft Magic, HP:Shipwrigth and Great Tower, Covenants and C&G. Thanks for any insights!
Earth as mud lvl 15 - Base 3 change stone/dirt into mud, +1 T, +1 Diam., +1 Part, +1 Size - The spell can change the hardness of 10 m3 stone or 100 m3 earth to be as soft as mud. The effect can be used to soften the terrain as long as stone columns can be sunk into the building site as support columns for foundation. 10 m3 of changed stone is equal of a 5 paces (meters) deep cylinder shaped mudpit with half a pace (50 cm) in diameter.
Metal and Stone, I Give You New Form! lvl25 Re Te - Base 3, +1 Touch, +2 for flexibility of shape and material, +1 for excessive details, +2 Group(or +1 Part and +1 Size? ) - The spell can shape 10 m3 of stone, mortar or 1 m3 of metal. Given a block of stone, bars of metal or a Part of a mountain, this enchantment with Rego craft magic shapes and cuts the materials to create the correctly formed metal items, building stones, be they part of a column, a ceiling rose or a fully-formed statue. The dimensions of stone blocks or columns are determined by the caster, just as the form of metal items. A Per + Finesse stress roll is required to control this spell against an Ease Factor that increases with the complexity of the pieces. Item Ease Factor:
An even stone block, a plowshare or iron nails 9
A column drum, iron tools or a shortsword 12
A ceiling vault rib, a statue, a longsword or a lock 15
The Creo requisite is required as the spell does not simply process or rearrange components but perfectly shapes the stone in order to do its work.
The Eldritch Carpenter lvl20 Re He (Pe) - Base 4, +1 T, +2 Group, +1 flexibility of shapes - The spell can work and shape 10 m3 wood. The magus selects a pile of wood, and the spell cuts, splits, carves, and joins the wood into the desired form. Any nails needed must be supplied, but wooden dowels can be formed from the supplied wood. The magus must make a Perception + Finesse roll to determine the success of the process. The Ease Factor is at least 3 higher than a carpenter’s Craft roll would require, so the simplest basic items have an Ease Factor of 6, increasing as the task gets harder. EF vs 9+ (as daily work of a semi-skilled craftman) is to provide good quality timber.
The Unseen Spirits of Stone and Wood lvl20 Re Te (He) - Base 3, +1 T, +1 Conc, +2 Group, +1 for Herbam materials - The spell can move and control 10 m3 of stone, mortar or wood, or 1 m3 of metal. The caster can move the stone, wood or metal parts of a building to their places, join them as required. EF vs 9+ (as daily work of a semi-skilled) for building a 10 m3 part of a wall. EF vs 12+ if the section has any special feature like archs or delicately shaped windows. EF vs 15+ for an instant stone-walled town house or precisely form the stone archs of ceiling which supports the next level of the building.
For Quality Control:
Feel the Heartbeat of the Monument lvl25 In Te (He) - Base 4, +1 T, M, +3 Structure, +1 excessive information - The caster can sense every detail about the stability and structural integrity of the target building. You know what is the weakest point in a building, how and where it needs to be strengthened. You know the "force lines" where the structure wants to be closer to the center of Earth and you know how to fix the structural problems of the building.
Separate the Poor Wood lvl10 In He - Base 3, +1 T, M +2 Group, - The caster gains a general knowledge about a pile of wood being touched. It can be determined which one is good for carpentry and which one is unsuitable for building purpose.
