OK, the power set of Galadriel in my opinions, I think about that after discussions in another thread, but I don't want to paste it there and cause it locked.
(1)LV1: Ring of Nenya: Once activated, for 15 seconds heal all nearby allies slowly, cancelled all negative effects(poison, Nazgul's influence,etc) and extinguish fires nearby.
(2)LV3: Lady of Lorien: Passive, all hero near Galadriel collect experiences 10% faster; Unlock different power of Mallorn tree in Lv 3,5,7,10.
Lv 3: Fruits of Yavanna: For 10 seconds, all Mallorn trees with economic upgrades would generate 20% more resources, the leaves of trees will shine in golden.
Lv 5: Whispers of Estë: For 10 seconds, all Mallorn trees would generate a deep fog, healing nearby units, slow down the motion and power recharge of nearby enemy units.
Lv 7: Defence of Caras Galadhon: For 10 seconds, all Mallorn trees with lv 1 defence upgrades would provide 30% defense bonus for nearby allies, all trees with Lv 2 defence upgrades(with archers) deal double damages.
Lv 10: Girdle of Melian: For 10 seconds, all Mallorn trees are invulnerable, they would be surrounded by whirlwinds of golden leaves and throw every enemy units to sky(Remember the final power of Celeborn from 3.8.1)
All these powers need recharge again once one of them is activated.
(3)Lv5: Gifts from Lorien: Strengthen other heroes, basically same as 3.8.1.
(4)Lv7: Light of Earendil: For 5 seconds, all nearby enemies flee with terrors, enemy heroes cann't use their power.
(5)Lv10: Cleansing the filthy: Like earthquake of Dwarves, this power will affect buildings in a large area, for 10 seconds decline enemy buildings armor for 66%, all
arrow towers cann't attack. The visual effect will be like Gloin's power of shaking the foundation.
Once acquired the ring, if she chooses to accept the ring and becomes the dark queen,
(1)Lv1: Foul vitality: the dark queen regain 50% of health, all units nearby(both friendly and enemy)slightly lose some health.
(2)Lv3: Queen of Darkness, passive, all friendly units nearby deal 25% more damage, but will give 20% of their experience to Dark Queen. Only one power of Mallorn tree
is available, all Mallorn trees generate dark fog for 15 seconds, damaging all enemies nearby and regaining health and healing nearby units by doing so.
(3)Lv5: Desperate Love: cast on one of enemy hero, enemy hero will fight for the dark queen for 15 seconds(uncontrollably) and give all experience to the dark queen.
(4)Lv7: Terror: For 10 seconds, all units except heroes(friendly and enemy) near dark queen are shocked(ignore the fearless), dark queen got a large area attack and 50% more defense.
(5)Lv10: Curses of Mandos: Cast in a large area, all buildings in this area are destroyed immediately, for 30 seconds these building slots cann't be used. However, the Dark Queen will lose 5% percent health for every building she destroyed.
If she declined rings and remain Lady Galadriel, Frodo and Sam will be summoned, won't mention their power here, her Lv7 power will become:
Lv 7, Might of light lady, Galadriel herself emits bright light, have the same effect of "Light of Earendil" and also make friendly units invulnerable for 5 seconds.
All her power and powers of Mallorn trees recharge 10% faster. She gains a magic shield just like Gandalf.
