Well, basically a highly flammable liquid, that when lit, will make fire go on tiles that have vegetation (i am not sure whenether hearth is vegetation tile or not) until they hit some tile without vegetation (road, water, plowed ground) afterward the ground would be bit bare(, and have maybe charred trees, maybe not) which would be easy to plow (almost no stamina loss while plowing)
The fire would move "quite" slow still, like 30 second to move from tile to tile, so that people could outrun it... unless somebody uses wind behind it (or vice versa, uses wind to slow it down or go other direction)
I know that this idea has darn alot griefing possiblities, but i had to submit this... it would be darn evil tactic to use if we ever get to such phase of game that we have nations and nation wars
So... on scale from 1 to 10, how good my idea seems? and do you have any other ideas for that kind liquid?
EDIT: well, the one way i could think balancing this would be to make it only affect for certain time after which all flames die... suddenly!
the time would be something about 1 min... and to burn grass you would need alot rare and expensive materials, but the outcome would be very fertible land area of which 1st couple harvests of something would be more productive ( 1 more seed, or grow faster, or give more leftover items, like flax) at certain %(maybe about 30%) so that it wouldnt be TOO overpowered.
Also make it so that the fire could be stopped easily by walking over it, if there are no other things stopping it.... or making claim option of not allowing fire near the claim (magical claim protector fairies?)
well, i know this is bad suggestion, but i still try develope it somehow...
