Lurid Layered (ScrapTD)

Lurid Layered is the fifth barrel in ScrapTD and is automatically unlocked.

Strategical use
Lurid Layered was a hellish weak barrel first, but got stronger and is a true kiler now. With the abilities speed, freeze or clone it can cause lots of damage, because the enemy will usually not be able to build Double Pains yet. It can also be used as a simple scrap production boost, before starting to use Coal, It's Alive or Danger Zone.

In the lower arenas it is even better, because of being the last automatically unlocked barrel and only one defense is automatically unlocked (Square Blue). Purchasing Double Pain costs 200, +600 from the defenses before, so it's rare to find players which can defend it in arena 1. But as of the recent update, DP can be purchased after Shooting Box, costing 400 bricks in total to get it, so sometimes players in arena 1 may have a chance of beating Lurids.

The best way to cause extreme damage to your foe is by sending It's Alive and Not Black first, then sending this barrel underneath those barrels to tank for the Double Pain defences your opponent has. However, it can also force Defence Boost of your opponent if they're expected not to have enough scrap to go for Tesla Tower to pretty much handle the threat, since Tesla costs 150 million scrap to get up, it would defend the cheap air barrel rush but is too expensive to go for during the midgame.

Overall use
Lurid Layered is the third strongest barrel as of the 1.1 update, because since Airstrike does like no damage to it, it is ridiculously strong and can synergize well with abilities which can cause extreme damage to your adversary.

It has good speed, it has a decent amount of HP and damage, and ground defences cannot target it because it is the first air barrel you'll get for half a million cost worth of scrap. Even one or two Double Pains cannot handle consistent Lurids very well!

Trivia

 * It's the third barrel which is the ultimate killer as of 1.1, second being Not Too Fresh and the first being Thor.
