Shion is a very complex character lol. I can help try and explain her. Her base skin uses 4 different kinds of funnels, each having their own purpose both active and passive abilities. The gravity funnel (top right) active deals 1 damage, and the passive gives you 2 block. The matrix funnel (bottom right) active deals 1 damage, and the passive gives you 1 matrix charge (once you get 16 matrix charge, all funnels attack twice and activate their passive ability twice). The dissecting funnel (top left) gives you stacks of reigns of war (which are a buff, it looks like a blue circle, found under your health bar and it gives you stats every turn based on how many stacks of reigns of war you have), the passive of dissecting applies debuffs to the enemy once based on how many stacks there are (it scales non-linearly for the thresholds). And finally the pursuing funnel (bottom left) active deals 1 damage, and the passive applies 1 stack of pursued to the enemy, which deals damage to it based on how many pursued stacks it has on the enemies turn. Each of these funnels can be upgraded by the card "Funnel Upgrade" which allows you to select which funnel you want to upgrade. Once you do that, you need to play 5 funnel cards (has the orange text "Activate *****" where the ***** is whatever funnel you want to activate). once you complete the task, your funnel upgrades and the passive is increased by 1 for every 3 upgrades (so there is a passive upgrade at level 1, 4, 7, 10, etc). Her relic "Dimension Splitter: Aria" takes 4 turns to charge up, and when you activate it (by right clicking it) it deals 10% enemy max health damage, and if it kills, it activates again and gives you an energy. Her second relic she starts off with "Concord: Snipe" increases the damage an enemy takes by 1 each turn (I think this only applies to physical damage, not funnel damage, so whatever is done by your funnels does not count). It also starts off with increasing the damage you take by 50%, and decreasing your outgoing damage by 50%. You decrease these values by 1% for every floor you climb, to a maximum of 50. You can also speed up this decrease of incoming and increase of outgoing by going to a rest site and choosing the "Reduce Time&Space Synchro by 3%". I forgot to mention that you can choose an active funnel once per energy you spend per turn (I only choose the gravity funnel to be my active because of how much shield it gives me). Some of the other Shion skins have skill points you can use, so you can fill out a skill web that make you a lot stronger, but the base skin doesn't have any skill points I think. Let me know if this makes any sense or helps out at all. I'd be glad to speak over discord if you have any other questions about any of the other characters, because I have figured them out as well
