I am afraid that by the time you are able to craft ballistas you will already have access to spelltowers.
I think the actual problem is how long it takes to level up the skill. If you are going to defend big base with it I think you are doing it wrong. You can only use normal arrows in ballista, which deal 55 damage to a target without any armor and can be easily avoided. They advertised that ballista is meant to be a step before you acquire spelltowers.
No easy maintenance that makes grind less what i actually had hoped for Goblin ballista was never meant to be an endgame mean of defense for a large base. So we are again facing massive grinding to maintain something in this game (next to farms, shields, towers and farming for iron hook arrows). And if you have a larger base that amount isn't even remotely enough to even cover every direction with a single ballista. Originally posted by Tr4ckzs:The issue isn't obtaining a decent amount of contracts like 50 or more, the issue is that you will burn through them in only a few days if you have more than 10 ballistas.
