Adding to chill’s point, I don’t think he intends for EVERY shrine to be in town. Probably 1 around the camps, 1 in the mountains and 1 in dust bowl or something
While this is cute, if we are to reference both fantasy and real world magic, they require more than just the blood of a caster.
Take satanic magic IRL for example: black candles, symbols, alters, words of power, group/ritual casting, commanding demons, human sacrifice(PSA: not actual killing, just death of a bad part of a person to banish X.), etc. you don’t have to believe it works yourself, but there are books you can read on the subject, like Anton Szandor LaVey’s “Satanic Bible”.
“White magic” uses animal sacrifice in place of the human, so they are using blood/death energy, while Satanism says it’s more important for the caster to be in a state of strong emotion, and project magic from the self. With the aid of supporting components, of course(sage, candles, incense, black robes, minimal light)
In a less exotic example, dungeons and dragons breaks magic down into about 7-8 designated magic ‘classes’, and within each there are different rules: bards can play an instrument/sing/use words of power, a wizard refers to a grimoire (book of spells), a sorcerer calls upon innate magical power gifted from the universe, etc. however in all cases, under normal circumstance, spells have other requirements:
- Casting time
- Components(verbal, gestures, or ingredients)
- Spell type(ritual/infusion/cantrip/normal spell)
- Concentration on a maintained spell
- Visibility or awareness of target/effect
And sometimes more.
Certain classes gain the innate skill to use specific magic without the requirements, but that would be the equivalent of using a Township Tale skill slot for using checkpoints… ick. Even if they made a new slot wheel for magic spells, ick, probably WAAAY better choices.
So, all of this said, I think just permitting users to innately use checkpoints detracts from the power & value of magic. And it lets brand new players use checkpoints when they have minimal magic within them/nothing to offer the shrines.
Rather than require a specific skill or spell to use the shrines, I would think using ingredient components and gestures (hand on rock) would be more than balanced for setting a checkpoint. Using your Crystal example:
Pull 1-25 crystals(depending on scaling value of shrine distance from town) from bag in 1 hand, shake like firebug to glowstick charge the crystals, smash crystals hand into ingredient intake, hand rock glows a ‘ready’ color, and anyone can activate it(or the activator only if that’s preferred, but I assume people would like to cover their friends cost & easily demonstrate it for others…)
