I know I'm very inactive, but I really want to help the developers from stop squeezing their mind, so here's the thread we want to post suggestions on spell appearances and more.
Format:
...Appearance/Spell Name/Spell Effect/Spell Logo
.:.Appearance/Secondary Spell/Secondary Spell Effect/Spell Logo

For mine:
...Bible/Group Heal/Heals all units by 20% of health/A large green cross and two small red cross
.:.Cowboy hat/Soil Erosion/Make a targeted area slow down the enemy's speed by 15%/A spinning soil

mass petrification, stone all of your opponent's unit, gg lol jkjk

Auto-activates when your statue is at 20% health. Stones your own units too. Offers free units to both sides.

Lots of units/Reinforcments/Gives 1 of each unit, can only do 5 min in a game/Stick wars 2 game.

Dragon/Dragon Ritual/sacrifice a Giant and summon a Dragon, the dragon is your new unit, so you can control it, it is always on your side untill it is dead/Dragon head with two swords which cross each others.

buff banner/slightly raises attack power of all units in desired area/ a sword and spear forming an X while a magikill staff and a shadowrath staff form a cross in between followed by bows pointing outward in the corners

How strong is the dragon???

Skeleton/ Hardcore / Reduce both player's statue health to 25% of its current value / Bloody Skull

Shaking ground/Earthquake/Half The Health of all units currently on the battlefield/Earth elemental

wow u guys r creative lets see here...(i think each faction should have its own set of spells idk if this will happen but if so here is wat i got and i don't care it someone else already posted one of these ideas)

ORDER:
( idk difference between appearance and logo i think its wat the king will look like so ill skip it) /family's fortune/instant 500-700 gold/a solid gold-bar (shiny)
i agree with bible but maybe a bit more than 20% like 30%
monument to ORDER/30%defensive boost 2 all units(yours) in radius between your castle and middle tower/a statue of a king giving a gift to a miner
from rebels to allies OR forgiven traitors/provides a meric, shadowwrath, and (random) either two swordwrath or 1 archidon/two bloody swordwrath shaking hands
old alliances/provides a magikill, spearton, and two miners /a magikill and a spearton bow 2 each other
FIGHT FOR JUSTICE!/provides a SMALL giant and a albowtross /a magikill killing a chaos giant
bloodoath/4 of your units that died in last 7 seconds come back 2 fight again but random/a spearton with a sword in his heart rising up again

CHAOS!:
ancient people/free 300 mana OR 2 free upgrade (random)/a picture of a medusa coming from the ocean(idk lol)
hell on earth/each enemy units takes damage total to 30% of max hp(counter bible)/a city burning
soul of CHAOS!/each unit (in your control) in radius of opponents castle and middle tower/a inferno burning inside of a chaos unit(idk which 1)
dark-arts/spawn a dead and a marrowkai/marrowkai summoning deads from their graves ritual
speed of destruction/spawn 6 bombers AND/OR(idk) 4 crawlers/a statue crumbling from bomber blasts
mutated race/spawn an eclipsor and a medusa OR a SMALL GIANT/a humble swordwrath changing into a giant
enslavement/take 1-3(idk 1st i though miners but now....) of the opponents units for your own side/a miner being shackled
MEDUSA'S RAGE!/(auto)upon reaching 30% statue health and only having 3 military units 1/2 or half of the opponents miners AND military units turn 2 stone AND provides a free juggernaut Medusa that has the stats of a SMALL giant BUT ACTS ON A COMBINATION OF PROGRAMS AND COMMANDS(will stay until death like in story mode but weaker)/a red Medusa head
blood pact/2 selected units die but in return 2 enhanced ghost spawns spawn from their corpse and fight for a set time or until death /a Medusa soul coming back for revenge (idk)

ELEMENTALS:
(i dont know much since there not released but i can try also think duh elemental lol)
FLASH FLOOD/ stops temporarily unit building que and upgrades being purchased as well as sending all enemy units right outside there castle (including miners resets commands)/a castle right before a tsunami hits
BLIZZARD/freezes all opponents low tier units and ones below 50% hp rendering them useless in ice (but revives a 40% defensive boost ) and slows down other units attack rate and speed by 20%./a frozen bomer and swordwrath
LIGHTNING STORM/ random enemy units get blasted by lightning dealing 40% max hp damage(may arc arced/chain-lightning only does 20% the storm last a few secs)/a magikill in the middle of casting electric-wall but then getting zapped (LOL)
INFERNO/all enemy units ignite dealing damage over time more effective and often than poison but disappears after a while/a bomer running around on fire trying to get out of it(how ironic)
EARTHQUAKE/ all enemy units momentarily stunned and damaged/a dead being sucked back into the ground from whence he came(how ironic....again)
TORNADO/a castle archer/dead dies and the rest is combination of flash flood teleport units back 2 castle (only a few) and a few random deaths OR SOMEKINDA COMBO ALL OTHER ELEMENTAL POWERS BUT WEAKER!!

THANK YOU FOR CONSIDERING IDEAS OF MINE ALTHOUGH THEY MIGHT BE HARD TO PROGRAM THERE JUST IDEAS TY! :D
HOLY SHIT I TYPE A LOT!!!!!!!!!!!!!!!!!

Volcana of poison erupting/Venom strike/Poisons all units in a gigantic area (1/3 of grass hill)/Medusa

Barrage/grants an extra castle archer for 5 seconds, attacks at super speed but no splash damage (can kill 3 speartons)/a group of archidons (mabey 5 to 7)

Arrow rain/ rains arrows that may or may not hit the enemy , arrows do as much as castle archer without splash damage, spell only affects desired area and can only be used behind the middle tower/ a rain of arrows
