The only spell in the game that benefits from this card is WildBolt.. Why would there be a trainable secondary school spell that is only good for Bolt?
Every school has either 90% accurate spells, or 15 or more % accuracy boost from gear. This is to say that even Storm spells at 70% accuracy become 100% accurate with an Accurate card(15%).. Even Sniper is pointless on anything besides WildBolt. What is the point of bringing these spells into the game? Is KI trying to encourage Spam Bolting?
The only players in the game who could possibly benefit from these cards in the PvE side of the game are low level players who don't have accuracy boost gear yet. These players, however, don't have access to the astral school trainers, or the Celestia library to purchase the cards. Even if they did have access to these things, they don't have enough training points and can't come across Gold easily enough to afford them often enough to be of any real help.
So my question is, what is the point of Unstoppable? Is it really just a boost for WildBolt?
I can't think of anything at all that it would help with besides that. Maybe casting a spell from your secondary school? But it would have to be a Fire or Storm spell for the card to even be necessary. Even then, probably better to put Elucidate on it and be able to cast it for a reasonable pip cost.
What's the point, really?
