+## Advanced combos ##
+
+Two ways of upgrading
+    #1 -> combine more of the same for a stronger version of the same skill / spec (T2 / T3 Combos)
+    #2 -> combine skill with two matching colour specs to change the way the skill works (Spec / Skill hybrid)
+
+### T2 / T3 Combos ###
+
+All current specs / items can be further combo'd into T2 and T3 versions
+
+# 3 of same base => 1 upgraded tier #
+`3 x T1 Red Damage Spec => T2 Red Damage Spec`
+`3 x T2 Red Damage Spec => T3 Red Damage Spec`
+`3 x T1 Strike => T2 Strike`
+`3 x T2 Strike => T3 Strike`
+
+Upgraded skills will have a combination of higher damage / longer duration / reduced cooldown
+Upgraded skills use the same speed formula as previously
+
+### Spec / Skill hybrid specs ### 
+
+# Strike #
+2 x Red Damage + Strike => Strike damage bonus (crit?)
+2 x Red Speed + Strike => Strike reduces enemy speed
+2 x Red Life + Strike => Strike reduces enemy healing (% reduction)
+
+# Heal #
+2 x Green Damage + Heal => Heal target for additional 20% of caster's maximum life
+2 x Green Speed + Heal => Heal target gets bonus speed
+2 x Green Life + Heal => Heal increases target's max hp for 2 turns
+
+etc etc
+
+30 skills * 3 specs => 90 spec / skill hybrid specs -> might be overcomplicated
