Loot bonus farming in Champs
No, it's not using barch to 50% a base, but rather making an army that costs less than what the loot bonus will give back to crush a base (th9 bases only, to be specific. Don't go for th10's with infernoes). You will need to next a bit often to find a th9.
Army composition: Giwiva
16 giants (Level 6)
12 wizards (Level 5)
9 valks (Any level)
8 wallbreakers (Level 5)
4 archers (Level 5+, for that 50% or 70% clutch, just in case)
Any clan castle troops, although I recommend high DPS troops such as valkyries, wizards and giants. Healers can also work
2 heals
4 earthquakes
1 poison
1 CC poison or earthquake, depending on your needs
Both heroes recommended, although it can still work without either or both of them
Cost: 168k to 175k elixir + ~1500 DE (varies depending on troop and spell levels)
Takes up to 1h 15m to make, up to ~18m with boost
If you need more DE profits, you can replace earthquakes with 2 jumps or 1 jump and 1 rage, however, this will affect total training time
This army is deployed similarly to a gowipe army (and about the same strength, too), only with golems replaced by giants, and pekkas replaced by valkyries.
1. If possible, lure enemy clan castle troops with a giant
2. Use 4 earthquakes to open compartments in a way that lets your troops access the first layer without the use of wallbreakers; depending on the base layout and spell placements, you can go straight into the core easily.
3. Make 2 groups of 8 giants several tiles apart to tank the wizards
4. Make a line of wizards behind the giants to create a funnel for your heroes and valkyries.
5. Drop heroes and valkyries once all outside buildings in that area are destroyed.
6. You can either drop your wallbreakers along with your valkyries, or save them for until the near-end of the raid if necessary. They tend to stray off and die when doing the former, therefore I recommend the latter*
7. Use heals when your giants and/or valkyries are under fire by wizard tower, or when they reach the core.
8. By step 6 or 7, the enemy clan castle troops (if any/applicable) with be after your troops. Drop a poison spell on them when they're close enough to hit your troops. Otherwise, you can use the poison spell on the enemy king or queen, if necessary.
Using this strategy, I was able to get all 5 builders active along with a lab upgrade. I currently have less than 1 million gold (just used my last builder to upgrade wizard tower), 6.4 million elixir and 22k DE (just started a lab upgrade)
*Former is the first idea, latter is the second idea, in case you don't know what these two terms mean
