could try keeping all vowels (a,e,i,o,u) in boiler and transmuting other not vowel letters ..... that way more damage output each word..*NOTE:never tried this myself but it makes sense so dont blame me if it doesnt work
hope this helps ^^ at the start increase ur turret and shield but keep engine at half the value of turret , then when turret reach 25 which is the same as shield upgrade both turret and shield but still keep engine at half the value, also remember to look at the radar at the start of each wave to make sure u don ram into a horde of minions..........lastly to defeat boss just wipe out all the minions before u focus on the boss.....STOP where u are and wait for the boss to reenter the radar then simply just MOVE ASIDE as the boss move mostly in a straight line(don forget to shoot it)....+ if this helps
