doing something that requires allot of work with angering (micromanagement and time) for 100k is not worth it
go with my method and get 120-160k easily without much micro management on most maps below 50 and 60 waves (you should play the earliest ones, that you did not replay yet, not just random maps), no angering needed and you won't get overwhelmet because you angered to much
Glaring difficulty with banishment, faster waves and beacon traits set to 7 (sometimes you have to reduce the faster wave trait a bit if you get overwhelmed at later waves) is an good and easy way to farm the early maps, as it gives more XP than looming with full traits by a factor of about 2,25, and costs as much in shadow cores, and you don't need to enrage anything unless you see that you start lacking some mana in later waves
you can just play on x9 speed on most maps most of the time with some breaks to upgrade or cast spells, it's important to keep upgrading gems (or sometimes only 1 of the 9 gems so you can kill higher armor creatures easiyl)
I normally go with 9 mana leech/armor shred dual gems, sometimes with 1 or 5 traps with slowing gems of grade 4 if needed, because they increase the damage the shooting
you can spare the enrage till later wizard levels when you want to get higher scores and replay earlier maps
I did this since about lvl 40-60 (I have 32*7 achievements thought, giving me a few extra "levels"
I was going with looming and max traits and enraging earlier but just going with 9x speed through a level without having to deal with super giants and even getting more xp is much easier
you can always go achievement hunting for some easier ones, on older maps if you need some extra skill points (remember that 7 achievements are already as good as 1 wizard level)
http://gemcraft.wikia.com/wiki/Achievements_(GC2)
my skillpoints are
9,12,15 (the best divisible by 3 you can go) into "true colors" (the extra damage basically makes your gems twice as valuable because 1 grade higher gives 60% more damage)
up to 17 into "masonry" (because this makes up for the lost mana directly at the start) unless you have a map with plenty of preset towers that can be used for a cheap formation of:
tower=t amplifier=a
t- t- t
a-a-a
t- t- t
or
t-a-t
t-a-t
t-a-t
9 or 12 into gemcrafting skill (because the combine cost is the domination factor at that level and in the early game)
maximum into mana gain from monster kills, because it just pays of
all in all
9,12,15 into gem damage and specials for dual gem damage (true colors)
max masonry until 17 because it pays of directly
9 or 12 into gemcrafting skill (9 if not enogh starting mana)
only if you have enough starting mana:
6 into mana gem mastery
6 into armor shred mastery
6 into slow gem mastery
6 into amplifier mastery
and 6,9 or 12 for the spells needed in tome levels
