ershiqi:

• always make sure there’s more than one layer
• a layer of invisibility shield helps hide you from most entities; makes you harder to be found (personally smoke and fog is good for this)
• cleanse your space thoroughly before putting up wards, you don’t want to be stuck with negative energy and entities
• it doesn’t always have to be spherical (you can make it tight fitting to your body like a second skin, it can be trapezoid for all i know)
• don’t forget you’re 3D so you have to ward your back and feet and top of head too
• you can incorporate different elements and types of shields (bouncy, rubbery, hard, flexible, airy, fiery, etc), try to match it with your energy
• you can also take inspiration from fiction (you want to make a shield that spins like naruto’s rasengan??? go ahead)
• asking for help from your deities/spirits you’re working with is also possible (to strengthen it, to add a little more oomph to it, or even to create a whole new layer)
• be creative and liberal with your creations because spiritual attacks happen in a lot of different ways
